Application:
Nozzle flowmeter is used for flow measurement of liquid medium in close pipeline. An orifice plate installed in line creates a pressure drop. This difference of pressure is measured via impulse line by differential pressure transmitter. The relationship between the rate of flow and pressure drop is very well known and allows to easily convert measured pressure difference to flow value.
Flowmeters without correction are used for mediums with constant values of pressure and temperature. For custody transfer measurement it's recommend to use differential pressure transmitters without SQRT characteristic and correction from changes of medium's pressure and temperature. This kind of measurement have to be calculated in dedicated flow counters.
Characteristic:
* High accuracy of measurement in wide range of flow
* Resistant for aggressive media
* Work in wide range of temp. and pressure
