When the frequency oscillator is con-

nected and an output is displayed on

the electronic readout device, this indi-

cates that the turbine flowmeter cable

assembly is defective and should be

replaced. If no output is displayed, the

turbine flowmeter cable assembly is

good and the problem lies within the

electronic readout device.

Checking the Electronics

Using the frequency oscillator and

the cable that is supplied, connect

Symptom

No output is

displayed or

registered

More volume/

output than

displayed or

registered.

Less volume/

Troubleshooting Reference Guide

Probable Cause

Defective magnetic pickup

Foreign matter obstructing the

turbine flowmeter rotor

Defective turbine flowmeter

internals

Defective turbine flowmeter

cable assembly

Defective electronic/readout

device

Rotor may drag due to foreign

matter obstruction

Magnetic pickup not screwed

down all the way into the

turbine flowmeter body. Caus-

ing it not to detect all the rotor

blades as they pass.

Turbine flowmeter installed

backwards.

Turbine flowmeter rotor in-

stalled backwards.

K-factor is too high in elec-

tronic/readout device.

Caused by entrained air in the

process line.

K-factor is too low in

electronic/readout device.

it to the electronic readout device,

the same as you would a turbine

flowmeter cable assembly. Once the

frequency oscillator is connected, if no

output is displayed on the electronic

readout device, check to ensure that

the power is on, the fuses are good,

and the correct K-factor is dialed/

programmed into the electronic

readout device. After verification of

these items, if there is still no output

displayed and/or registered, then the

manufacturer of the electronic readout

device should be consulted.

Solution

Refer to the Checking the

Magnetic Pickup section.

Refer to the Checking the

Turbine Flowmeter section.

Refer to the Checking the

Turbine Flowmeter section.

Refer to the Checking the

Cable Assembly section.

Refer to the Checking the

Electronics section.

Refer to the Checking the

Turbine Flowmeter section

Screw the magnetic pickup all

the way down into the turbine

flowmeter body. Hand-tighten

only.

Install the turbine flowmeter in

accordance with the process

flow direction.

Install the turbine flowmeter

rotor in accordance with the

process flow direction.

Verify K-factor used. K-factor

should be decreased.

Install an air eliminator up-

stream of turbine flowmeter.

Verify K-factor used. K-factor

should be increased.
