Full-channel-width flow meter

Abstract

The invention provides a full-channel-width flow meter which comprises a flow meter box body, wherein a front opening facilitating liquid inflow is fixedly formed in the front end of the flow meter box body, and a rear opening is fixedly formed in the rear end of the flow meter box body; a control box which is internally provided with a controller and a data processing module, wherein the controller is electrically connected with the data processing module, and the control box is fixedly arranged at the upper end of the flow meter box body; multiple liquid level sensors which are sequentiallyarranged on the inner wall of the flow meter box body, wherein the liquid level sensors are electrically connected with the data processing module in the control box; multiple flow velocity sensors which are sequentially arranged at the bottom of the flow meter box body, wherein the flow velocity sensors are electrically connected with the data processing module in the control box; and an excitation module, wherein the excitation module is electrically connected with the controller. The full-channel-width flow meter is high in measurement accuracy, wide in application range and wide in use range.

Description

technical field [0001] The invention relates to the technical field of flow velocity measurement of conductive liquids, in particular to a full-channel wide flowmeter. Background technique [0002] Electromagnetic flowmeters are flowmeters that measure flow according to Faraday's law of electromagnetic induction. The advantage of the electromagnetic flowmeter is that the pressure loss is extremely small, the measurable flow range is large, the applicable industrial pipe diameter range is wide, its output signal is linear with the measured flow rate, and the accuracy is high. , Alkali, salt solution, water, sewage, corrosive liquid and fluid flow of mud, pulp, paper pulp, etc. [0003] The traditional throttling device, building water measurement, gate hole outflow open channel flow measurement method has a large head loss, which affects downstream water use; for water measurement with low flow rate, branch, bucket, and hair channel, all kinds of water measurement equipment ...

AI Technical Summary

Problems solved by technology

[0003] The traditional throttling device, building water measurement, gate hole outflow open channel flow measurement method has a large head loss, which affects downstream water use; for water measurement with low flow rate, branch, bucket, and hair channel, all kinds of water measurement equipment in the past required on-site calibration. However, it is very difficult to obtain the true value of on-site calibration, so the problem of traceability of the value is difficult to solve

Moreover, the existing electromagnetic flow sensors only measure at a single point, and the accuracy is not high
