SP-LDE Water Plant Sewage Flow Meter, Online Monitoring Sewage Flow MeterIntegrated intelligent flow meters are widely used in industries such as petroleum, chemical, metallurgical, textile, food, pharmaceutical, papermaking, as well as environmental protection, municipal management, water conservancy construction, etc., including water, sewage, mud, pulp, various acids, alkalis, salt solutions, food slurries, etc.
Water plant sewage flow meter, online monitoring sewage flow meter Product features:
1. Measurement is not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity;
2. There are no obstructing flow components or pressure loss inside the pipe, and the requirements for straight pipe sections are relatively low;
3. Series nominal diameter DN15~DN3000. There are multiple options for sensor lining and electrode materials;
4. The converter adopts a novel excitation method, with low power consumption, stable zero point, and high accuracy. The flow range can reach 1500:1;
5The converter can be integrated or separated from the sensor；
6. The converter adopts a 16 bit high-performance microprocessor, 2x16 LCD display, convenient parameter setting, and reliable programming;
7. For a bidirectional measurement system, it is equipped with three integrators: forward total, reverse total, and difference total; Can display. Zhuang, reverse flow, and have multiple outputs: current, pulse, digital communication HART；
8. The converter adopts surface mount technology (SMT) and has self checking and self diagnostic functions;

1. Classified by purpose (see Table 1)

Table 1

2. Classify by combination type

According to the combination of converters and sensors, there are two types: split type and integrated type.

3 Main structures

The electromagnetic flowmeter consists of two parts: a sensor and a converter (as shown in the figure below).

The sensor is mainly composed of measuring tube, electrode, excitation coil, insulation lining, housing and other parts.

Selection Example 1：

The measuring medium is 31% hydrochloric acid, the pipeline material is plastic lined pipeline, the pipeline diameter is DN50, the display mode is integrated, and the output signal 4-20mA corresponds to an upper limit flow rate of 20 cubic meters.
Selection instructions: As the measuring medium is dilute hydrochloric acid, the lining of the liquid receiving part is selected as polytetrafluoroethylene, and the electrode material is selected as tantalum electrode. Due to the non-conductive material of the pipeline, a three electrode configuration is chosen.
Selection Example 2:
The measuring medium is treated wastewater, the pipeline material is plastic pipeline, the pipeline diameter is DN200, the display mode is split type, and the output signal 4-20mA corresponds to an upper limit flow of 150 cubic meters.
Selection instructions: As the measuring medium is sewage, the lining of the liquid receiving part is selected as rubber, and the electrode material is selected as stainless steel electrode. Due to the non-conductive nature of the material used to connect the pipeline, a three electrode configuration was chosen.
Selection Example 3：
Measurement medium phosphoric acid, pipeline material is carbon steel pipeline, pipeline diameter is DN80, display mode is split type, output signal 4-20mA corresponds to upper limit flow rate of 60 cubic meters.
Selection instructions: As the measuring medium is phosphoric acid, the lining of the liquid receiving part is selected as polytetrafluoroethylene, and the electrode material is selected as stainless steel electrode. Due to the conductivity of the material used for pipeline liquid connection, a two electrode configuration was chosen.
