Type EP turbine flow meters are used for the precise measurement of small flow rates of fluids. They are suitable for both measuring the actual flow rate and total flow. The turbine should be installed in a vertical position with outlet up. Smoothing interval up- or downstream of the meter is not necessary, fittings with pipe reducers may be installed right at the meter. Also, pressure impact does not affect the performance of the EP meter. The simple mechanical structure guarantees for a long lifetime with constant accuracy.

• A high number of pulses per volume unit provides high resolution

• Linear measuring range wider than 1:15 for viscosities up to 5 mm²/sec

• Response time of 3 to 5 msec thanks to the low mass of the sailwheel
