Difference between waist wheel flowmeter and Roots flowmeter
The utility model is characterized in that a measuring chamber is arranged in the shell of the flowmeter, and the measuring chamber is provided with a pair of or two pairs of waist wheels which can be rotated by tangency. A pair of driving gears are coaxially arranged on the outer side of the flow meter shell and the two search wheels, and they are meshed with each other so that the two lumbar wheels can be linked with each other.
The waist wheel flowmeter, also called root flowmeter, is the same kind of product, and there is no difference between them.
The waist wheel flowmeter is mainly used for measuring the flow of large bore gas, liquid and steam medium in industrial pipelines. Flowmeter is characterized in that the pressure loss is small, large measuring range, high accuracy, influence of the measuring condition of volume flow rate is almost not affected by fluid density, pressure, temperature, viscosity and other parameters, so no moving mechanical parts, high reliability, small amount of maintenance. Instrument parameters can work stably for a long time. The plug-in type wheel flowmeter adopts piezoelectric stress sensor, which has high reliability and can work in the temperature range of -20 DEG C to +250 centigrade. It has analog standard signal and digital pulse signal output, which is easy to use with computer and other digital system. It is a kind of advanced and ideal flow meter for waist wheel flowmeter.
