Intelligent LDE-250 Electromagnetic Flow Meter LDE-250 Electromagnetic Flow Meter Direct Sales

Description :

　　This product can measure the flow rate of dirty media, corrosive media, and suspended liquid-solid two-phase flow. This is because there are no flow obstructing components inside the instrument measuring tube, and only the inner lining and electrodes of the measuring tube are in contact with the measured fluid. The material can be selected according to the properties of the measured fluid.

　　1、 Characteristics

　　Small size, light weight, easy installation, and low maintenance;

　　Wide measurement range, unaffected by changes in fluid temperature, density, pressure, viscosity, conductivity, etc;

　　It can be installed by drilling holes on old pipelines, with simple construction and installation, and a small amount of work;

　　Compared to general electromagnetic flow meters, it has lower costs and installation expenses, making it particularly suitable for measuring flow in large and medium-sized pipelines;

　　Adopting advanced processing technology, solid-state packaging, long service life, and ensuring good measurement accuracy and stability of the instrument;

　　Simple structure, sturdy and reliable, long service life (and suitable for measuring seawater);

　　There are no moving parts or resistance parts inside the measuring tube, no pressure loss, and no blockage will occur;

　　Reliable measurement and strong anti-interference ability.

　　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. Electromagnetic flow meters should be installed at the lower and vertically upward positions of horizontal pipelines, avoiding installation at high points and vertically downward positions of pipelines;

　　2. The electromagnetic flowmeter should be installed at the rising point of the pipeline;

　　3. When installing an open discharge pipeline, it should be installed at the lower part of the pipeline;

　　4. If the pipeline drop exceeds 5m, install an exhaust valve downstream of the sensor;

　　5. Electromagnetic flow meters should be installed with control valves and shut-off valves downstream of the sensor, rather than upstream of the sensor;

　　6. Sensors should never be installed at the inlet and outlet of the pump, but rather at the outlet of the pump;

　　7. The method of installing an electromagnetic flowmeter in the measuring well.
