Open channel flowmeters measure the flow of liquids that are open to the atmosphere at some point in the measurement system.
Toshbro Controls Open Channel Flow Meter - 'Nivoson' is a non-contact ultrasonic transmitter that offers accurate and reliable flow measurement in open channels.
The transmitter has the formulas for 20 commonly used flumes and weirs which allows for a fast set-up. In case of custom built weirs with unknown level and flow relation, a 32 bit linearization function allows for accurate measurement. The instrument offers 2 Flow totalizers for volumetric flow measurement. One of the totalizers is resettable while the other is not.
