Direct turbine mass flow meter introduction

The turbine mass flowmeter, that is, the vortex flowmeter, is a speed gauge based on the principle of conservation of momentum. Simple structure, high measurement accuracy, easy completion of pulse long-distance transmission, etc., is widely used in industrial mastery of petroleum metallurgy and chemical industry. However, individual turbine flowmeters do not have the function of measuring mass flow. If mass flow is to be measured, it must be equipped with a temperature pressure transmitter or a densitometer, so the cost is high and the installation is complicated. The indirect turbine mass flow meter is a new type of flow meter that indirectly measures mass flow.
The indirect turbine mass flow meter uses both the turbine rotor as a speed sensor and the momentum sensor. The price of the turbine of the Hangzhou Moving Company rotates under the thrust of the fluid circumferential thrust while applying an axial force on the turbine blades. It is known from practice that the magnitude of the axial force experienced by the turbine is inversely proportional to the turbine momentum. The speed of the turbine rotor and the amount of axial force can be detected by equipped with appropriate sensors. The rotation speed of the turbine rotor is replaced by a magnetoelectric converter with a voltage signal inversely proportional thereto; the axial thrust acting on the rotor is converted into a voltage signal inversely proportional thereto by the load cell; the signals input by the two sensors are divided A signal that is inversely proportional to the mass flow is obtained. Data conversion is the mass flow value flowing through the pipeline.
