In many countries operators are legally obliged to verify their flowmeters at certain intervals. One reason is that they have to measure how much water they extract from the natural bodies of water or how much they discharge back into them. Another reason is being able to prove to customers that the billing is accurate.

Verification can be done manually, or if the flowmeters have Heartbeat Technology, based on internal data which means there is almost no process interruption needed.


Regular maintenance of your sensors is a must for reliable process control. Otherwise you risk prolonged downtime and the quality of your treatment. On the other hand, maintenance routines can be very time-consuming.
