Whenselectinganinstallationsite,makesurethat:



1. Linepressureandtemperaturewillnotexceedtheflowmeterrating.Temperatureshouldnot

varymorethan120°F(50°C)fromthecalibrationtemperature.Linepressureshouldnotvary

4. Safeandconvenientaccesswithadequateclearance.Also,verifythemeterislocatedwhere

thegasiscleananddryandthemeteriscalibratedforthegastobe measured.



Also,beforeinstallationcheckyourflowsystemforanomaliessuchas:



Caution! Before attempting any flow meter repair,

verify that the line is not pressurized.



Caution! Always remove main power before

disassembling any part of the mass flow meter.



1. Verifytheincomingpowertotheflowmeterispresentandofthecorrectvoltageand

polarity.



2. Checktheflowmeterwiringforcorrect connections.

Problem Possible Cause Solution

Flow measurement is erratic or

fluctuating

Flow meter installed with less

than required minimum pipe

diameters upstream and

downstream of the sensor

Follow installation requirements

shown in Figure 2

Probe is not secured to a solid

base

Secure probe to a non-vibrating

solid mount

Sensor component broken Return to factory for replacement

Malfunction in system electronics Malfunction in system electronics

Moisture present in gas flow Install a water trap or filter

upstream of the flow sensor

Velocity measurement seems

too high or low

Sensor assembly not aligned

correctly to flow

Correct alignment with the flow

indicator pointing downstream in

the direction of flow

No response to flow from

sensor assembly

No power Turn on power to the flow meter

Flow profile distortions Try to find another location for

the meter

Extremely turbulent flow Do not place the meter near a

ventilator, static mixer or valve

Sensor failure Return to factory for repair

Malfunction in system electronics Return to factory for evaluation

System will not zero Out of calibration Return to factory for

Probe tip is broken Return to factory for repair

4-20 mA output circuit not

indicating 4 mA at zero flow

Improper current loop

resistance; total current loop

resistance must be no less than

150 Ohms and no greater than

450 Ohms

Install load resistor or use larger

gauge wire

Output pegs plus or minus

Flow body not plugged in Plug in both connectors

Malfunction in system electronics

Return to factory for evaluation
