CFW30 Gas flow velocity measuring instrumentDetailed product description：

The CFW30 turbine gas flow velocity measuring instrument is a speed type instrument that has the advantages of high accuracy, good repeatability, simple structure, few moving parts, high pressure resistance, wide measurement range, small volume, light weight, low pressure loss, and easy maintenance. It is used to measure the flow velocity and volume flow rate of low viscosity gases in closed pipelines. Its good measurement accuracy and excellent repeatability have made it widely used in natural gas trade and transportation measurement at home and abroad by Qufu Huaqiang Mining Equipment Co., Ltd. The CFW30 gas flow velocity measuring instrument is an intelligent measuring instrument used for measuring the flow rate and flow velocity parameters of gas drainage pipelines with a diameter of DN80-DN400. The speed measuring component adopts a "turbine", and on the basis of retaining the original advantages of the turbine, Qufu Huaqiang Mining Equipment Company has improved it to meet the actual needs of coal mine gas drainage detection. It can be well applied to the measurement of flow rate and flow velocity parameters of single drilling conditions in the drilling site, as well as the measurement of flow rate and flow velocity values of mainline pipelines. It is an intrinsically safe instrument for mining, with an explosion-proof mark of ib Ⅰ (+150 ℃).

The main features of CFW30 gas flow velocity measuring instrument are:
⑴. Equipped with turbine flow velocity sensors, different pipeline flow coefficients are directly solidified in the software without the need for users to change, which can avoid the problem of inaccurate measurement data caused by inputting incorrect coefficients.
⑵ Convenient to use, users of Qufu Huaqiang Company only need to insert the speed turbine component into the reserved measurement hole in the pipeline for instant measurement.
⑶ Low resistance, with almost no impact on the gas flow field.
⑷ Good low-speed performance and high measurement accuracy.
⑸ It has an automatic shutdown function.
