ZENITH PUMPS 

Feedback Control by Using a Flowmeter with Frequency Signal 
(cont’d) 

5. Result: 

• 

The output from the pump will be controlled by the flowmeter 

• 

The units of the setpoint and the Tach are same as the unit of F

m

  

6. IMPORTANT NOTE: 

• 

The unit of the setpoint is in (cc/min), and 

no longer in (RPM)

 

• 

The pump speed may vary at very wide range. 

Do not to exceed the factory suggested 

speed limit

 

• 

Any restriction at the discharge side of the pump can rapidly increase the speed of 
pump.

 This is the major causation making the pump over-speed. Check any down-stream 

restrictions before the operation.  

• 

Always test the system without any  down-stream restrictions. Gradually increase the 
restrictions, and monitor the speed of the pump closely, to make sure not to over-run 
the pump

 

• 

The operation can make the pump runs at very high speed. You should test your sys-
tem for safety under all potential conditions. Failure to do so can result in damage to 
the equipment and/or serious injury to personnel
