Is it good idea to use ultrasonic clamp type of flowmeter for water dosing?
I already using the flowmeter pulse output by setting to 10L per pulse. Installation set-up was followed and signals seems working fine, flowrate reading seems on target at 2.9 liters per second (approximate equal during bucket test) This pulse output is fed to PLC digital input and have a program of Total Volume = Total Volume + 10.
The problem is, it is always off target. Actual volume either over or under the target.
I am starting to doubt if ultrasonic flowmeter can be used for dosing of liquid. Did anyone used the same type of flowmeter?
By the way, the conductivity of pure water that was used is less than 2 microsiemens that is why electromagnetic was not considered before.
