Industry Information
The scale of the stainless steel glass rotor steady on a cone at a certain height indicates the flow value of the fluid
2012-3-8 13:08:37

主要由一根自下而上扩大的锥形玻管和一只随流体流量大小上下移动的不锈钢浮子组成。 The stainless steel glass rotor flowmeter is mainly composed of a conical glass tube that expands from bottom to top and a stainless steel float that moves up and down with the size of the fluid flow. When the fluid flows through the cone from bottom to top, the lift force S generated by the fluid kinetic energy on the stainless steel float and the fluid buoyancy A cause the stainless steel float to rise. When the sum of the lift force S and the buoyancy A equals the gravity of the stainless steel float G, the stainless steel float is in equilibrium , Stable at a certain height position, the scale on the cone indicates the flow value of the fluid. The stainless steel glass rotor flowmeter flange, float, guide rod, support plate and bolts are all stainless steel 304 (1Cr18Ni9Ti), SKLZB-() B. SKLZB / LZJ series stainless steel glass rotor flowmeters are widely used in chemical, petroleum, light industry, pharmaceutical, environmental protection, food and metrology testing, scientific research and other departments to measure the flow rate of single-phase non-pulsating fluids (liquid or gas).

的刻度,是生产厂在本厂条件下用近于理想流体的水和干燥空气作介质标定得到的。 The stainless steel glass rotor flowmeter is calibrated under the conditions of the factory using water and dry air that are close to the ideal fluid as the medium. However, there are two situations where the scale value of the flowmeter cannot be used directly: one is that the measurement medium is not water and air, and the other is that the medium is water and air, but its state (temperature, pressure) and scale The status is different. In this way, when using a flow meter, in order to obtain a correct measurement result, a problem arises that the scale value needs to be corrected. Therefore, solving the calibration of the glass rotor flowmeter is the key to using this instrument. Considering that environmental protection instruments use rotor flowmeters to measure the flow of gaseous media, only the density correction in gaseous media measurement is discussed below. Because the viscosity of the gaseous medium is small, the viscosity effect is omitted in the discussion. Practice has proved that this does not affect the accuracy after correction
