How to choose a rotor flowmeter?

Selection Notes

1. For the selection of remote output metal tube float rotor flowmeter, it is necessary to choose a rotor flowmeter that is suitable for the explosion-proof requirements of the application site; During installation, attention should also be paid to the fastening of the instrument casing and the sealing of the wiring ports after power on, to meet the requirements of explosion prevention, protection, and corrosion prevention. 2. For places where the temperature of the measured medium is too high (>120 ℃) or too low, insulation or heat insulation measures should be taken for the sensor part of the rotor flowmeter. To ensure the normal working environment temperature of the signal converter indicator, a high temperature indicator should be selected. 3. For some measured media that require insulation or cooling, a jacket type rotor flowmeter should be selected. The heat tracing or cooling interface of the standard metal tube float rotor flowmeter adopts DIN2501 DN15 PN1.6 flange connection. If other source car flanges or threaded connections are required, please specify

4. For unstable pressure of the inlet medium of the rotor flowmeter, especially for gas measurement, damping structure should be selected to ensure accuracy and service life. If other standards are used, please indicate

6. When installing the rotor flowmeter, the fan bureau should ensure that the verticality of the measuring tube is better than 5%, and a bypass should be installed for maintenance and cleaning without affecting production

7. The installation position of the rotor flowmeter should ensure that there is a straight pipe section of ≥ 5DN at the inlet and a straight

pipe section of ≤ 250mm at the outlet;

; If the medium contains ferromagnetic substances, a magnetic filter should be installed before the rotor flowmeter. The control valve in the measurement and control system should be installed downstream of the rotor flowmeter. When used for gas measurement, it should be ensured that the working pressure is not less than 5 times the pressure loss of the rotor flowmeter to ensure stable operation of the rotor flowmeter. Before installing the metal tube float rotor flowmeter, the welding slag inside the pipeline should be blown clean and tidy; During installation, remove the stop element from the rotor flowmeter; When using after installation, slowly open the control valve to avoid impact damage to the rotor flowmeter. Performance characteristics: Rotary flowmeter is the most commonly used flowmeter in industry and laboratory. It has the characteristics of simple structure, intuitive, low pressure loss, and easy maintenance. Rotary flow meters are suitable for measuring small flow rates through pipelines with a diameter of D<150mm, and can also measure the flow rate of corrosive media. When in use, flow meters are generally installed on vertically oriented pipe sections, and the fluid medium passes through the rotor flow meter from bottom to top. Specially designed rotor flow meters can be installed horizontally or vertically with upper inlet and lower outlet. Jiangsu Huaxia Instrument Technology Co., Ltd. is a high-tech enterprise that integrates product research and development, production, and sales of flow meters. The companys product LZZ metal tube rotor flowmeter is a metal structure float flowmeter suitable for measuring liquids and gases. The float moves upward under the ac
