Overview
The LDM-51 Series F-Type Non-Full Tube Electromagnetic Flowmeter is an automatic flow measurement instrument that utilizes the velocity-area method to continuously measure fluid flow in open pipelines (such as semi-tube flow channel outlet pipes and large flow pipelines without overflow weirs). It can measure and display instantaneous flow rate, velocity, and cumulative flow data. Particularly suitable for metering needs in irrigation water pipelines, municipal stormwater, wastewater, and sewage discharge.
The LDM-51 Series F-Type Non-Full Tube Electromagnetic Flow Meter is an automatic flow measurement instrument that utilizes the velocity-area method to continuously measure fluid flow in open conduit pipelines (such as outlet pipes of semi-tube flow channels and large flow pipelines without overflow weirs). It can measure and display instantaneous flow rate, velocity, cumulative flow, and other data. Particularly suitable for measurement needs in irrigation water pipelines, municipal rainwater, wastewater, and sewage discharge.
Features
Suitable for measuring flow rates in open-ended non-full-bore pipelines (round pipes, rectangular pipes, or other irregular shapes).
■ Achieves bidirectional flow measurement, both forward and reverse.
The sensor operates reliably for extended periods in harsh field conditions and wastewater water quality.
Flow rate measurement range: 0.01-10 m/s
High flow measurement accuracy, unaffected by downstream, backwater, blockage, and other factors.
The instrument features complete display and output functions, capable of showing instantaneous flow rate, velocity, cumulative flow, and so on, and comes with a computer communication interface 232, 485 (optional).
■ With optional GSM and GPRS wireless data transmission capabilities;
■ Features power failure timing, counting, and a clock function.
