MST100-Wall Mounted Digital Display Flow Controller

MST100 is the flow meter in tight, wall mounted case (IP 65), designed to work in tandem withthe pulse flow transducers with coefficients ranging from 0.01 to 9999.99 pulses per litre,equipped with electronic (open collector) or contact input. A flow meter allows to measure the actual instantaneous value and to record the total flow of fluids, gases or bulk materials. Wide range of total flow enables flow volume control for a long time. Build in a batcher function makes possible application of MST100 in a wide range of industry branches (food production, pharmacy，paint and varnish). The counters may have 2 relay (or OC) outputs, depending on the actual instantaneous, batcher or total value of the flow (R1).
