The LDS electromagnetic water meter is a battery-powered electromagnetic induction water meter which can be installed anywhere without sacrificing accuracy and performance. It does not require the main power supply.It is specifically designed for individual water applications such as water withdrawal, pipe network distribution, metering charges and irrigation. It has intelligent information and high measurement performance, which is easy to install and saves user investment.
1. The meter is easy to install: the meter can be buried underground or installed in the well. The IP68 (NEMA6P) design is not affected by the installation position of the meter in the pipe, and no filter is required.
2. Low pressure loss: the straight-through measuring pipe ensures minimum pressure loss, even at the highest flow rate, which reduces the pressure of the entire network system, and it helps prevent the pump from being over-pressure, causing the pipe to rupture and leak.
3.Zero maintenance: use the design of no moving parts, and battery life can reach five years.
4. Two-way measurement: use only one meter for two-way flow measurement.
5. Intelligent type meter:use only one meter for leak measurement, data record function and error self-test.
