　　The installation methods of this product are divided into two types: pipeline type and plug-in type. Both types consist of sensors and intelligent signal converters, which can be divided into two structures based on the assembly form of the converter and sensor: integrated and separated; One salary type: The converter and sensor are directly assembled as a whole and cannot be separated - commonly used in sites with good environmental conditions. Split type: The converter is composed of a dedicated cable and a sensor to form a product, with the sensor installed on site and the converter installed in a well conditioned field. Commonly used in sites with poor environmental conditions, such as underground wells, high temperatures, and places that are difficult for personnel to reach. Pipeline type is generally suitable for measuring the flow rate of larger diameter pipelines.

　　1、 Performance characteristics:

　　The instrument 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 types: integrated and separated.

　　High definition LCD backlit display.

　　3、 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.

　　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.
