I. Product Overview
The non-full-pipe electromagnetic flowmeter is an automatic flow measurement instrument that uses the velocity-area method to continuously measure fluid flow in open channels. It can continuously measure instantaneous flow rate, flow velocity, cumulative flow, and other data in open non-full-pipe pipelines. It is particularly suitable for metering applications under non-full-pipe conditions such as municipal stormwater, wastewater, sewage discharge pipelines, and irrigation water pipelines. The non-full-pipe electromagnetic flowmeter consists of a compact measurement system comprising an electromagnetic velocity sensor, an ultrasonic level gauge, and a flow converter, which continuously measures the flow velocity and liquid level of fluid in open non-full-pipe pipelines. The user only needs to input the inner diameter of a circular pipe or the width of a rectangular pipe, and the non-full-pipe electromagnetic flowmeter will automatically calculate the flow rate in the pipeline and automatically display measurement parameters such as instantaneous flow rate, flow velocity, and cumulative flow.
II. Functional Features
Can be used for flow measurement in open non-full-pipe pipelines (circular pipes, rectangular pipes, or other irregular-shaped pipes); Can be used for continuous measurement in municipal stormwater, wastewater, sewage discharge, and irrigation water pipelines; Supports automatic bidirectional flow measurement in both forward and reverse directions; The sensor can operate reliably over the long term under harsh field conditions and sewage water quality; Wide flow velocity measurement range of 0.01 m/s to 15 m/s; High flow measurement accuracy, unaffected by downstream backwater, blockage, and other factors; Large-screen, backlit LCD display ensures clear readability of measurement data whether in strong light or at night; Comprehensive display and output functions, capable of displaying measurement data such as instantaneous flow rate, flow velocity, cumulative flow, and liquid level in the pipeline; Equipped with computer communication interfaces 232, 485 (optional); Equipped with GPRS wireless data remote transmission function (optional); Equipped with power outage timing, counting, and clock functions.
