　　Anti corrosion LDE-80 electromagnetic flowmeter

　　1. Overview:

　　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. For example, using polytetrafluoroethylene or polytetrafluoroethylene as lining 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.

　　2、 Characteristics:

　　1. Wide range of measurement.

　　2. In addition to measuring the volumetric flow rate of general conductive liquids, it can also be used to measure strong corrosive liquids such as strong acids and alkalis, as well as mud, slurry, and pulp.

　　3. A bidirectional measurement system that can measure both forward and reverse flow rates.

　　4. The measurement results of electromagnetic flowmeter are independent of physical parameters such as pressure, temperature, density, viscosity, conductivity, and are not affected by the environment.

　　5. Reliable performance, high accuracy, low power consumption, stable zero point, and convenient parameter setting. Click on the Chinese display LCD to show accumulated flow, instantaneous flow, flow rate, flow percentage, etc.

　　4、 Installation:

　　1. Horizontal and vertical installation

　　Sensors can be installed horizontally and vertically, but it should be ensured to avoid the influence of sediment and bubbles on the measuring electrode, and the electrode axis should be kept horizontal. When installed vertically, the fluid should flow from bottom to top. The sensor cannot be installed at the highest position of the pipeline, as this position is prone to the accumulation of air bubbles.

　　2. Ensure full pipe installation

　　Ensure that the flow sensor is filled with the measured fluid in the pipeline during measurement and that there is no non full pipe state. If the pipeline is not full or the outlet is empty, the sensor should be installed on a siphon tube.

　　3. Installation between bends, valves, and pumps

　　To ensure the stability of the measurement, a straight pipe section should be installed in front and behind the sensor, with its length given in the following figure. If it cannot be achieved, a current stabilizer should be used or the cross-sectional area of the measurement point should be reduced.

　　4. Sensors cannot be installed at the inlet of the pump

　　To avoid negative pressure, the sensor should not be installed at the inlet of the pump, but at the outlet of the pump.

　　5. Inlet and outlet straight pipe sections of the sensor

　　An ideal installation location should be chosen with sufficient straight pipe sections before and after the measurement point. The inlet straight pipe section should be ≥ 5D, and the outlet straight pipe section should be ≥ 3D (D is the nominal diameter of the sensor). The inserted inlet straight pipe section should be ≥ 20D, and the outlet straight pipe section should be ≥ 7D (D is the nominal diameter of the sensor).

　　6. Installation when the pipeline outlet is empty

　　When the outlet is in an empty state, the sensor should not be installed at the point where the pipeline is empty, but at a lower position. When the sensor is installed below the pipeline, it should be ensured that the sensor is filled with liquid and there should be no empty tube state.
