Product Description
1.GeneralRoots flow meter is a kind of intelligent PD flow meter. The accuracy can reach as high as 0.2%. This kind of flow meter is easy to be disassembly and re-calibrated after a period of operation.
This kind of roots flow meter features smart structure and wide flow rangeThe meters are widely used for the flow measurement in the field of petroleum, chemical, chemical fiber, traffic, food industries and commerce, medical and sanitary departments.Temperature compensation and pressure compensation is optional.2.operation principleIn the measuring chamber, a pair of roots wheels and cover plate make a crescent shape cavity which is used as a measuring element.
The roots wheels are rotated by the pressure difference in the inlet and out-let of the meter and drive the inlet liquid through the cavity to the outlet, each revolution of the roots wheels displaces fluid four times the volume of the cavity, the total revolutions of the roots wheels and the revolution rate will be transferred to the mechanical counter, and the total liquid volume and instantaneous flow will be known by the pointer display and the roller integration.
The attached signal generator converts the rotary axial angular shift to the pulse signal and then transmits it to the electrical indicator for remote integrated flow and instantaneous flow indication and control.
