Digital gas liquid flow meter vortex flowmeter
Digital gas liquid flow meter vortex flowmeter can measure the flow of gases, liquids and steams within the range of routine flow and be set by switches to adapt to various measuring medium of various calibers; can immediately display the parameters of instantaneous flow rate, cumulative flow rate, frequency, temperature, pressure, etc.
Digital gas liquid flow meter vortex flowmeter is based on the principle of the Karman vortex to measure the volume flow rate of gas, vapor or liquid. It adopts the advanced differential technology, cooperating with isolation, shielding, filtering etc method to make it in good shock resistance ability and without small signal disorder problem, also using special sensor sealing technology to guarantee its high reliability.
