Deertaba flow sensor is used to measure the flow rate through the differential pressure devices. Measure the flow of liquids, gases and steam and other fluids. With no moving parts, virtually no pressure loss, easy installation and maintenance, low running costs. Is detected by the sensor lever taps and guide rods, pipe it across the inside of the tube axis perpendicular to the surface facing the flow measuring rod is provided with a plurality of taps to measure the pressure of the average of the total, at its back, sidestream face a measuring hydrostatic pressure taps, respectively, by the total pressure and static pressure guide tube connecting pipe leads, according to the differential value of the total pressure and static pressure, the calculated flow through the pipeline. Can also be used instead of the static pressure sensor rear wall flow stream surface static pressure. Deertaba flow meter measurement system is composed of sensors, impulse accessories and differential pressure transmitters, pressure transmitters, temperature transmitters, flow converters and other ancillary component. You can calculate the mass flow or volumetric flow and heat and mass energy. Deertaba flowmeter is within GB / T2624.1-2006 and JJG640-1994 national design and manufacturing standards for measuring fluid flow based on pipeline.
