Flow meters

The pressure connect ion can be tapped or threaded. The output signal can be made in analog 0-10v, or 4-20mA, and in frequency. The flow measurement is carried out on the Karman Vortex path principle (pressure variations caused by vortices). As an option, the flowmeter can integrate temperature measurement via a PT1000, or CTN (Negative Temperature Coefficient), or 0-10v, or 4-20mA probe. These flow meters do not have moving mechanical parts and therefore are insensitive to pollution. They have a low pressure drop and very good precision. The choice of a flow meter depends on several factors such as the type of fluid to be measured, the temperature of the environment and the fluid, the output signal, the accuracy of the measurement which varies from 1% to 2% depending on the range of measured.
