PARITY TURBINE METER AND PREAMPLIFIER ASSEMBLY FEB 2013

INTRODUCTION 1-1

1.0 INTRODUCTION

1.1 Meter Description

The Daniel Parity Turbine Meter is a volumetric flow measuring device that produces high

resolution signals directly proportional to the rate of liquid flow through the meter. These signals

are amplified and shaped by an internal preamplifier mounted directly on the meter. The meter can

accommodate up to two signals that can be transmitted to accessories such as totalizing counters,

digital readout devices, or control equipment for interpreting data.

The Daniel Parity Turbine Meter is available in sizes from ½ inch to 16-inch with bidirectional

components available for some models. The meter is designed for use within the guidelines and test

procedures of API Standard Chapter 5.3.

1.2 Specifications

Please see the specifications on page 2-9 through 2-11.

SERIOUS PERSONAL INJURY OR DEATH POSSIBLE

Do not operate this equipment in excess of the specifications listed.

Failure to heed this warning could also result in damage to equipment.

PARITY TURBINE METER AND PREAMPLIFIER ASSEMBLY FEB 2013

INSTALLATION 2-1

2.0 INSTALLATION

Although your meter may be mounted in either a horizontal line or vertical line flowing upwards,

the recommended installation is horizontal with the pickoff on the side in an outward facing position

rather than on top. This is the standard factory calibration position. Side mounting the pickoff will

prevent condensation from settling in the pickoff well. Review the information below prior to

installing your meter.

2.1 Flow Considerations

A properly designed flow system will do two basic things toward maintaining the linearity of the

turbine meter. It will properly condition the incoming flow so that it is homogenous throughout its

cross section and it will provide proper back pressure so that cavitation will not originate inside the

meter.

Linearity can be defined as the total range of deviation of accuracy expressed as a curve, between

minimum and maximum flow rates. The ideal accuracy curve of a volumetric meter, such as the

parity turbine, is a straight line denoting a constant meter factor.

Cavitation is the formation and collapse of vapor-filled cavities that result from the sudden decrease

and increase in pressure.

MECHANICAL EQUIPMENT DAMAGE

Provide unobstructed upstream piping.

Flowing liquid encountering a restriction or change of direction may result in damage to

adjacent surfaces in meters, valves, pumps and pipes.

Parity turbine meter performance depends, to a great extent, on the incoming fluid being devoid of

swirls and excessive turbulence. These conditions can be avoided by providing unobstructed piping

upstream of the meter. Pipe fittings such as elbows and tees, and piping components such as valves

and strainers should be located far enough upstream as to allow for the dissipation of any flow

disturbance before it reaches the meter. Use of flow straighteners or a flow conditioning plate greatly

influences meter performance.

FEB 2013 PARITY TURBINE METER AND PREAMPLIFIER ASSEMBLY

INSTALLATION2-2

2.1.1 Specific Gravity

The parity turbine meter is affected by specific gravity and may influence performance. The effect

of specific gravity on the meter may be evidenced when specific gravity drops below 0.66. As

specific gravity decreases, the lift force on the turbine blade decreases. Likewise, as velocity

decreases, lift force on the turbine blade decreases. These reduced lift forces are overtaken by

bearing friction as low rates are approached. Subsequently, linearity deteriorates at low flow rates

while measuring light fluids.

To compensate for separate meter factors at low rates, electronic monitoring equipment is used. This

has been proven to enhance the overall measuring accuracy at the load rack and other like

applications. As low flow startup and shutoff flow rate is encountered, an established meter factor

for that flow rate is applied. During the time that the high flow rate is used to load the bulk of the

measured volume, a meter factor established for high flow rate is applied.

2.1.2 Viscosity

Turbine meters are viscosity sensitive in that as the metered fluid increases in viscosity, meter

linearity begins to suffer. This effect on linearity is primarily due to a change in the fluid's velocity

profile and skin friction between the fluid and the rotor blades.

In order to maintain turbine meter linearity on viscous fluids a high ratio of inertial to viscous forces,

known as Reynolds number, must be obtained. It should be noted that the turbine meter typically

performs best in turbulent flow conditions as opposed to laminar flow. A high Reynolds number is

one of the factors needed to maintain turbulent conditions.

The Reynolds number is a dimensionless number defined as:

Re=DuP ÷ µ

where D = inside diameter of the pipe

u = mean flow velocity

P=density of the fluid

µ =dynamic viscosity,

all in consistent units.

PARITY TURBINE METER AND PREAMPLIFIER ASSEMBLY FEB 2013

INSTALLATION 2-3

2.1.3 Seasonal Changes

For optimal performance, where hydrocarbons are metered and where there is a large temperature

swing from summer to winter, it is recommended that a new meter factor be established as seasons

change. This is recommended since temperature affects viscosity and viscosity affects meter

performance.

Generally speaking, viscosities of 3 centipoise or less give no cause for concern. Above this

viscosity, all influential factors should be considered. By properly anticipating the flow system's

viscosity, maximum flow rate, flow range, and desired linearity, the user can properly apply the

parity turbine meter to the required application.

2.1.4 Back Pressure and Cavitation

It is preferable that the turbine meter be used with a centrifugal pump and that it work against a

constant back pressure. The back pressure must equal:

• the pressure drop through the meter, plus

• the vapor pressure of the flowing fluid at the operating temperature and pressure, plus

• a minimum of 15 psi (103 kPa).

This will ensure there is no cavitation in the meter that could result in rotor over-speeding. Rotor

over-speeding will accelerate wear and damage the rotor. Frequency output from the meter during

cavitation is not a valid measure of the flow rate since flow meters are designed to measure liquids.

The minimum pressure at the outlet of the meter may be calculated using the following expression.

be

P . 2ªp + 1.25 p

Where:

b

P = minimum back pressure, pounds per square inch gauge (psig).

Îp = pressure drop through the meter at the maximum operating flow rate for the liquid

being measured, pounds per square inch (psi).

e

p = equilibrium vapor pressure of the liquid at the operating temperature, pounds per

square inch absolute (psia), (gauge pressure plus atmosphere).

FEB 2013 PARITY TURBINE METER AND PREAMPLIFIER ASSEMBLY

INSTALLATION2-4

2.2 General Considerations

Before installing a new meter, pipelines should be flushed thoroughly to rid them of welding bead,

pipe scale, and other debris. This can be done using a spool piece in place of the meter. Note the

direction liquid should flow through the meter indicated by the plate on the inlet flange, and install

the meter downstream from pumps.

Always use a flushing medium compatible with the metallurgy of the meter and its internal

parts, and similar to the product the meter is intended to measure.

2.3 Valves

The metering system should have a flow control valve located at a convenient distance downstream

of all measurement equipment. The function of the control valve is to limit and maintain system

pressure on the meter. This avoids cavitation.

When a meter is being calibrated with a displacer type prover (one using a piston or sphere) a back

pressure valve should also be used downstream of the proving device. This valve can be a simple

manual valve that is partially closed. A minimum pressure of 12 to 15 psi (83 to 103 kPa) should

be maintained downstream of the prover.

Valves should be capable of rapid, smooth opening and closing with positive shutoff.

• When used for intermittent flow, valves should be fast acting and shock-free.

• Spring loaded or self-closing valves should be of the type that will open to admit air when

hydraulic hammering or vacuum conditions occur.

• Bypass lines should be equipped with blind or positive shutoff devices.

• Shutoff or control valves should be located downstream of the meter.

PARITY TURBINE METER AND PREAMPLIFIER ASSEMBLY FEB 2013

INSTALLATION 2-5

2.4 Flow Straightening

For proper operation of the meter a flow conditioning plate, flow straightener (designed for the

meter), or a straight run of pipe (20 pipe diameters long) is required. All piping must be the same

diameter as the meter and should contain no flow restricting devices which could cause reversal of

the flow straightening effect.

2.5 Flow Conditioning Plate

The flow conditioning plate is available for all new or retrofitted 2", 3", 4", 6", 8" and 10" Daniel

Parity Turbine Meters. It is designed to eliminate product flow characteristics such as liquid swirl

and non-uniform velocity profiles (induced by piping configurations and other elements of the

system) that may impede proper measurement within the turbine meter run. It is installed directly

into the inlet of the meter and because of its flow conditioning influence on the incoming product,

reduces requirements for upstream flow straightening pipe. It is recommended that a minimum of

5 pipe diameters be maintained upstream of the meter and two pipe diameters downstream of the

meter, in addition to the Flow Conditioning Plate, to assure proper operation.

2.6 Strainers

A strainer of proper size should be installed upstream of the meter to protect it from the introduction

of foreign material which could damage the meter. Recommended sizes include: 40 mesh for refined

products, and 10 to 20 mesh sizes for crude products -depending on the product being measured.

Recommended strainer mesh sizes based on meter size can be found in Table 2-1.

INSTALLATION2-6

2.6.1 Strainer Monitoring

1. Recommended procedures dictate that regular, scheduled cleaning of the strainer basket be

conducted to prevent filling and rupturing of the screen.

2. Pressure gauges installed on both sides of the strainer will indicate differential pressure

across the strainer. High pressure differential, caused by filling the basket or occlusion of

foreign material can cause strainer basket rupture resulting in possible meter damage.

Table 2-2. Quick Reference Setup

Before You Install Your Meter

Before installing a new meter, some general considerations must be made.

1. The meter should be located away from electromagnetic fields that may interfere with proper

flow measurement.

2. Pipelines should be flushed thoroughly to rid them of welding bead, pipe scale, and other

debris. This can be done using a spool piece in place of the meter.

3. Note the direction liquid should flow through the meter, indicated by the plate on the inlet

flange, and install the meter downstream from centrifugal pumps.

4. Calculate the proper back pressure required for safe and accurate installation.

Refer to Section 2.1.4.

Back Pressure equals pressure drop through the meter, plus the vapor pressure of the

flowing fluid at operating temperature and pressure, plus a minimum of 15 psi (103 kPa).

5. Recommended installation is horizontal with the pickoff on the side and facing out; however,

the meter may be mounted vertically as the application demands.

6. Install a strainer, or proper mesh size, upstream of the meter.

7. Shut-off or control valves should be positioned downstream of the meter.

8. Isolation valves should be installed to facilitate meter maintenance.

9. Applications using turbine meters with flow conditioning plates require a minimum of two

pipe diameters downstream straightening. Conventional meters using flow straightening pipe

require 5 pipe diameters downstream.
