product overview
DC-LDE seriesElectromagnetic flowmeter for sewage treatmentIt is a new type of intelligent electromagnetic flowmeter developed by our company using advanced measurement and conversion technology at home and abroad to meet the extensive needs of current sewage treatment processes. In selecting the core components of the electromagnetic converter, a 32-bit high-speed embedded MCU processor imported from the United States is used, greatly improving the operating speed, accuracy, and reliability. Wide voltage, electrical isolation, power-off protection, lightning surge protection, etc. are also designed. Solved the functions of zero position manual and automatic adjustment, fault self checking, and alarm from a software perspective, not only achieving a longer service life of the instrument, but also making it more convenient for users to use. Improvements have been made in the mechanism, material selection, and process of electromagnetic sensors, strengthening the insulation and moisture protection of the coil, improving performance stability, and extending service life.
Product Features

The instrument structure is simple, reliable, without moving parts, and has a long working life.
There are no flow blocking components, and there is no pressure loss or fluid blockage.
◆ No mechanical inertia, fast response, good stability, can be applied to automatic detection, adjustment, and program control systems.
The measurement accuracy is not affected by the type of measured medium and its physical parameters such as temperature, viscosity, density, pressure, etc.
◆ Different combinations of PTFE or rubber lining and electrode materials such as Hc, Hb, 316L, Ti can adapt to the needs of different media.
There are various flow meter models available, including pipeline type and plug-in type.
Using EEPROM memory, the storage of measurement and operation data ensures safety and reliability.
◆ It has two types: integrated and separated.
High definition LCD backlit display.
