The ECH series screw flow meter is a very accurate double-shell liquid flow measurement device. The main body consists of a pair of spiral rotors and three chambers between the shells. It generates a high-resolution output signal proportional to the liquid flow rate through the flow meter via a sensor that is not in contact with the liquid.The signal is shaped and transmitted to auxiliary equipment by an internal preset amplifier, and the data can be indicated locally or remotely transmitted to the secondary meter through a transmitter.
The unique double-shell structure design can reduce the adverse effects of the external environment.
The maximum linear accuracy is ±0.05% and the maximum repeatability is 0.01%.
With a range ratio of up to 1:10 , under low flow conditions, the metering performance is also excellent.
It output the signal via a high resolution proportional generated via a sensor that is not in contact with the liquid that are proportional to the liquid flow rate through the flow mater.
Minimal pressure loss, can be installed vertically or horizontally, and the metering performance is not affected.
