Knowing the exact flow rate in various pipes or pumps can be
extremely useful information for any water or wastewater plant operator to
have. This can help you achieve smooth, cost-efficient, headache-free
operations. However, without installing a flow meter on a wide range of pipes,
this information can be hard to get.
Now, using the sensorless flow calculation function in the water
dedicated ACQ580 drive, you can quickly know the flow rates in your operations
and also detect possible leaks. There are two ways of using the flow
calculator: with or without pressure sensors. The user can thus define either a
power-flow or a head-flow performance curve as the basis for the calculation.
Compared to expensive external flow meters, the built-in
flow calculation function provides a simplified, cost-effective measure of water
flow with realistic accuracy. It can also detect leakages or no-flow situations
in a water system, and serve as a back-up to know the flow rates in your water
process if the main flow meter is under maintenance.
