Vertical screw conveyor problem

By the National Science and Technology, China Institute of Metrology Traffic Professional Committee, China Association of Automation Engineering Council and the China Nonferrous

Engineering and Research Institute and other institutions of the Consultative Group of Experts adopted the electromagnetic flowmeter, agreed that, liuliangjisjm the project

product is "HART" communication protocol technology, a private detective and measurement speed nozzle body integration design, private detectives new transformer-isolated

detachable ultrasonic transmitter and receiver, the products anti-interference ability, great range, especially in low flow and seismic performance and country has great

advantages compared to similar products, the main technical indicators have reached the international advanced level, to fill the field of measuring equipment technology gaps.
Currently, the main instrument screw conveyor vortex flowmeter, differential pressure flow meter, shunt rotor flowmeter, Annubar, float type flow meters, etc., where the main

discussion vortex flowmeter, orifice flowmeter and elbow flowmeter. As a new conveyor flow meter, developed rapidly since the mid-1980s, it has a lot of flow measurement

advantages and strengths, in the modern flow measurement more widely. The domestic use of vortex flowmeter for flow measurements are also increasingly get attention, present, Pharmaceutical metal detector

China has excellent performance and have independent intellectual property products. Vortex flowmeter is based on the fluid vibration developed, according to the vortex of

different detection methods from the hot wire type, thermal stress gradually developed a style, type and differential switched capacitor magnetic, ultrasonic, etc. Vortex

flowmeter can be used for almost all occasions form a vortex column, not only for the closed tube, but also for the open grooves. Compared with the turbine flowmeter, vortex

flowmeter has no moving mechanical parts, less maintenance, meter constant stability; compared with the orifice plate flowmeter, turbine flowmeter measuring range, small

pressure loss, high accuracy, installation and maintenance easy. However, vortex flowmeter parameters related to the environment are more likely to be ignored in the use of the Automatic Sorting Machine

site and affect the proper performance of flowmeters play.
