Operating instructions for LDE-500 electromagnetic flowmeter

Description :

　　This product can measure various corrosive media such as acids, alkalis, salts, etc; The use of wear-resistant rubber as an inner lining is particularly suitable for measuring liquid-solid two-phase flows such as slurry and cement slurry with solid particles and high wear, as well as various suspended liquids such as fibrous liquids and pulp.

　　1、 Technical parameters:

　　Nominal diameter (mm) (special specifications can be customized)

　　Pipeline type PTFE lining: DN10~DN600

　　Pipeline rubber lining: DN40~DN2200

　　Flow direction: positive, negative, net flow

　　Range ratio: 150:1

　　Repetitive error: ± 0.1% of the measured value

　　Accuracy level: Pipeline type: 0.5 level, 1.0 level

　　Temperature of the tested medium: ordinary rubber lining: -20 to+60 ℃; High temperature rubber lining: -20 to+90 ℃

　　PTFE lining: -30 to+100 ℃; High temperature PTFE lining: -20 to+180 ℃

　　Rated working pressure: (high pressure can be customized) DN10- DN150: ≤ 1.6MPa; DN200－DN350：≤1.0MPa

　　DN400－DN1000：≤0.6MPa； DN450－DN2200：≤0.25MPa

　　Flow velocity range: 0.1-15m/s

　　Conductivity range: The conductivity of the measured fluid is ≥ 5 μ s/cm

　　2、 Characteristics:

　　The structure is simple, reliable, without moving parts, and has a long working life.

　　No flow blocking components, 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 materials 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 forms: integrated and separated.

　　High definition LCD backlit display.

　　3、 Installation method:

　　1. Vertical installation, the sensor should be inserted into the pipeline at an angle of less than 5 ° to the vertical diameter of the pipeline section, suitable for measuring clean media with low pipeline vibration.

　　2. Tilted installation, with the axis of the sensor at a 45 ° angle to the axis of the measured pipeline, is suitable for measuring the flow rate of liquids with large diameters and other impurities in the measuring medium. This installation method has low water resistance and should not be tangled.

　　3. Clean the welding slag and burrs on the installation base of the tested tube.

　　4. Close the upstream flow control valve or use low-pressure water supply.

　　5. Pay attention to the long cavity of the ball valve facing upwards, check if the ball valve can be fully opened and closed, and install the clamping thread seat, clamping nut, and rubber sealing ring onto the ball valve.
