Section 1: Routine maintenance

1.1 Meter maintenance

This section includes discussion of the maintenance of Daniel 3812 Liquid Ultrasonic Flow

Meters.

For reference, you may download the Daniel MeterLink Quick Start Manual from:

http://www2.emersonprocess.com/en-US/brands/daniel/Flow/ultrasonics/Pages/Ultrasonic.aspx

SURFACE TEMPERATURE HAZARD

Meter body and piping may be extremely hot or cold

Wear personal protective equipment when coming in contact with the meter. Failure to do so may result in

injury.

TRANSPORTATION HAZARD

When moving the meter, do not insert the forks of a forklift into the bore.

Inserting the forks may cause the meter to become unstable, resulting in injury or damage to the bore and

sealing face.

CRUSHING HAZARD

During meter installation or removal, always place the unit on a stable platform or surface that supports

its assembled weight.

Failure to do so could allow the meter to roll, resulting in serious injury or equipment damage.

2 Meter maintenance

Section 1: Routine maintenance Maintenance and Troubleshooting Manual

February 2020 3-9000-767 Rev HB

Consult your Daniel Sales and Service representative to ensure you purchase the correct

components and seals for your application, below safety message,

TRIPPING HAZARD

Clear all obstacles or obstructions from the work area when transporting, installing or removing the

meter.

Failure to clear the work area may cause injury to personnel.

ESCAPING FLUIDS HAZARD

The purchaser of the meter is responsible for the selection of Daniel components/seals and materials

compatible with the chemical properties of the measurement fluid.

Failure to select suitable meter components/seals may cause escaping fluids, resulting in injury or equipment

damage.

Field hydrostatic pressure testing procedures 3

1.2 Field hydrostatic pressure testing procedures

The Daniel 3812 Liquid Ultrasonic Flow Meter can be field hydrostatic tested without any special

preparations or disassembly. The transducers are not exposed to the process pressure and can

remain installed in the meter.

The liquid ultrasonic meter pressure containing parts include, but are not limited to the

transducer housings. The Hydrostatic test is verification of the pressure containing capability of

the liquid ultrasonic meter pressure containing parts and seals. Each Daniel Liquid Ultrasonic

Flow Meter is successfully hydrostatic pressure tested prior to shipping from the factory.

The maximum field hydrostatic pressure test must be limited to 1.5 times the stamped

maximum working pressure. The maximum working pressure is stamped on the meter ID tag.

LEAKAGE OR PRESSURE CONTAINING PARTS FAILURE

Use precautions to eliminate hazards to personnel in the event of leakage or failure of

the liquid ultrasonic meter pressure containing parts or failure of the test equipment

and to prevent over-pressurization during the test procedure.

Failure to do so may result in injury to personnel or cause damage to the equipment.

A copy of this test is available by contacting Daniel Customer Service. Please provide the body

serial number when requesting a copy of the test report. The body serial number is located on

the downstream flange to the left of the hoist ring hole (when looking at the flange face).

Daniel Customer Service contact information is located on the back page of the manual.

Section 1: Routine maintenance Maintenance and Troubleshooting Manual

February 2020 3-9000-767 Rev HB

1.3 Routine maintenance

Routine maintenance operations requires adherence to all applicable regulations and laws and

safety training for personnel to perform the maintenance operations. Review your

organization’s best practices procedures before performing routine maintenance.

1.3.1 Maintenance logs and reports

To monitor the performance health of the meter, and ensure it is operating within acceptable

specifications, routine diagnostics should be performed. Collecting a maintenance log gives

you a snapshot of the current health of the meter and you can compare the inspection reports

from previously saved logs. Use the Logs/Reports menu and click Maintenance Logs and

Reports. Daniel MeterLink displays the Maintenance Logs and Reports dialog. Choose the time

duration, log format and collection rate for the output file and click the Start button. You can

open the file immediately after it is generated or view it at a later time. It is recommended that a

Maintenance log be collected after an upset in the system.

In establishing a baseline to be used for the trending of the meter diagnostics, it is very helpful if

a set of log files are collected immediately after the meter has been installed in the field.

Preferably, collect the log files at several velocities within the operating range of the meter. This

helps establish that the flow profile is relatively constant throughout the meters operating

range (except velocities below 3 ft/sec where the profile may vary).
