LDE-200 Electromagnetic Flow Meter Description

Description :

　　This product is suitable for flow measurement of industrial pipelines, channels, small rivers, and various conductive liquid measurements in environmental treatment. It is widely used in municipal water supply, steel, petroleum, chemical, power, industry, water conservancy, water administration, water resources and other departments.

　　1、 Characteristics:

　　The sensor adopts an integral welded structure with good sealing performance;

　　The structure is simple and reliable, with no moving parts inside and almost no pressure loss;

　　The measurement accuracy is not affected by changes in physical parameters such as pressure, temperature, density, viscosity, etc. of the measured medium; Accuracy is not sensitive to changes in velocity distribution (except for vortices);

　　Equipped with conductivity measurement function, it can distinguish whether the sensor is empty or not; Adopting a 16 bit embedded microprocessor, it has fast computing speed and high accuracy; There are two integrators inside, which display forward and reverse accumulation and difference accumulation respectively; Capable of outputting RS485 or RS232C digital communication signals.

　　2、 Technical data:

　　Nominal diameter series DN (mm)

　　Pipeline PTFE lining: 10, 15, 20, 32, 40, 50, 65, 80, 100, 125, 150, 200, 250, 300, 350, 400, 450, 500, 600

　　Pipeline rubber lining: 40, 50, 65, 80, 100, 125, 150, 200, 300, 350, 400, 500, 600, 800, 1000, 1200

　　Flow direction: positive and negative net flow. Range ratio: 150:1. Repeatability error: ± 0.1% of the measured value

　　Accuracy level: 0.5 level, 1.0 level (pipeline type)

　　Temperature of the tested medium: ordinary rubber lining: -20+60 ℃

　　High temperature rubber lining: -20+90 ℃

　　PTFE lining: -30+100 ℃

　　High temperature PTFE lining: -30+180 ℃.

　　Rated working pressure: Pipeline type: DN10-DN80 ≤ 1.6Mpa, DN100-DN250 ≤ 1.0Mpa, DN300-DN1200 ≤ 0.6Mpa

　　Flow measurement range: The flow measurement range corresponds to a flow velocity range of 0.1-15m/s

　　Conductivity range: The conductivity of the measured fluid is ≥ 5us/cm (integrated type). Most media composed of water have a conductivity in the range of 200-800 μ s/cm, and electromagnetic flow meters can be used to measure their flow rate.

　　Current output: When 0-10mA, the load resistance is 0-1.5k Ω; 4 Ω? At 20mA, the load resistance is 0-750k Ω

　　Digital frequency output: The upper limit of the output frequency can be 1? Set the transistor collector with photoelectric isolation to open circuit bidirectional output within 5000Hz. When the external power supply is ≤ 35V and conducting, the collector current is 250mA

　　Power supply: 85-265V, 45-63Hz

　　Length of straight pipe section: Pipeline type: upstream ≥ 5DN, downstream ≥ 2DN.

　　3、 Installation:

　　1. There should be no strong external magnetic field interference or strong mechanical vibration around the flowmeter. Before installation, the environmental conditions should be reviewed according to its usage requirements for normal use;

　　When installing the flowmeter outdoors, there should be a cover on the upper part to prevent rainwater from entering and direct sunlight from affecting the service life of the flowmeter;

　　3. The flowmeter can be installed at any angle, and the direction of fluid flow should be consistent with the direction indicated on the housing. There should be straight pipe sections of 10DN and 5DN upstream and downstream of the flowmeter, respectively;

　　4. The flowmeter should be installed coaxially with the pipeline, and the flange screw hole connection should be parallel to the pipeline axis to prevent sealing gaskets and grease from entering the pipeline cavity;

　　5. If necessary, a filter can be installed upstream of the flowmeter to filter out particles and debris in the medium.
