Low-power-consumption high-precision electromagnetic heat meter and mounting and use method thereof

Abstract

The invention specifically provides a low-power-consumption high-precision electromagnetic heat meter. The low-power-consumption high-precision electromagnetic heat meter comprises a mechanical rectifier body, an electromagnetic drive signal collecting structure and a control and display structure. The electromagnetic drive signal collecting structure is fixed to the front end of the mechanical rectifier body through a flange, the control and display structure is arranged outside the mechanical rectifier body and the electromagnetic drive signal collecting structure, and the control and display structure is electrically connected with the electromagnetic drive signal collecting structure. The low-power-consumption high-precision electromagnetic heat meter has the following advantages that the magnetic field intensity is large, strength is large, power consumption is low, and the overall efficiency of the low-power-consumption high-precision electromagnetic heat meter is improved; it can be effectively guaranteed that an excitation coil is stably fixed to the outer wall of a pipe, the arousal effect on liquid is better, and the measuring precision of the heat meter is improved; an integral structure is adopted, and therefore the pipeline liquid tightness is effectively improved; the Reynolds coefficient of fluid is reduced.

Description

technical field [0001] The invention relates to the field of flow metering equipment, and in particular provides a low-power-consumption and high-precision electromagnetic heat meter. Background technique [0002] Thermal fluid often contains air bubbles, turbulence, turbulence and other disturbances, which make flow measurement inaccurate. Especially for domestic heating pipelines, due to the narrow space and many pipeline bends, it is easy to cause unstable water flow and low measurement accuracy. The commonly used impeller heat meter in the technical field is low in production cost, but its measurement accuracy is low and its anti-dirt ability is poor, so it cannot be widely used; the ultrasonic heat meter has the advantage of easy installation, but it is easy Cause pipeline vibration, turbulence, air bubbles, dirt and other disadvantages, and then affect the measurement accuracy. [0003] Therefore, those skilled in the art urgently need a thermal fluid meter that is e...
