Abstract

The invention discloses a mass flow meter based on a weighing method. The mass flow meter comprises a container; the upper part of the container is provided with a water inlet, the lower part of the container is provided with a water outlet, and the bottom of the container is provided with a weighing sensor; and a flow guide and impact resistance device is arranged below the water inlet in the container. The mass flow meter can reduce the measurement error of the weighing sensor which is caused by liquid compact force during dynamic measurement of flow, and filter large impurity of water to solve the problem of blockage of pipelines and a water circulation system.

Description

technical field [0001] The invention relates to a weighing method flow measuring device, in particular to a weighing method based mass flow meter. Background technique [0002] The wells and springs used for seismic observation have their particularities. Generally, the source of groundwater is deep, the circulation path is long, the temperature is high, and the geological age is old. The water quality of such well springs is high salinity, high temperature, containing a large amount of gas, even corrosive gas, and some substances such as oil, sediment, etc., especially some artesian wells with stable groundwater flow field, the flow rate is relatively high. Small, belonging to the measurement range of micro and small flow. In the past 30 years, although the flowmeters that have been developed and put into use at home and abroad include velocity flowmeters, volume flowmeters, impeller flowmeters, differential pressure flowmeters, momentum flowmeters, groove flowmeters, and ...
