The correct installation of the sensor is the prerequisite for ensuring the accuracy and reliability of the measurement. If the error in the installation location and method selection affects the measurement accuracy, the severer one will affect the service life of the sensor and even damage the sensor.
1 Ensure proper straight pipe section
When installing the sensor, it is generally required that the length of the upstream straight section 15-40DN and the length of the downstream section 5DN can be appropriately adjusted according to the conditions of the upstream and downstream pipelines to ensure measurement accuracy. Sensors should also avoid installing sensors on very long pipelines that are overhead. After a long time, the sagging of the sensors can easily leak the seal between the sensors and the flange. If it is necessary to install the sensor, it must be located 2D upstream and downstream of the sensor. Separately install pipe brackets and other fastening devices.
2 to avoid strong vibration
The sensor should be avoided from being installed on the pipeline with strong vibration. If it is necessary to install it, vibration reduction measures must be taken. Pipe fastening devices are installed at the upstream and downstream 2D ​​of the sensor and a shockproof pad is added. The vibration at the compressor outlet is strong and the sensor cannot be installed. It should be installed after the gas tank.
3Select the appropriate installation method according to the measuring fluid
When measuring high-pressure air, you can choose to install the sensor on a horizontal pipe or a vertical pipe. However, if the moisture content in the high-pressure wind is high, the sensor should be installed at a higher position in the pipeline when installed horizontally, and the gas flow should be installed when installed vertically. From the bottom up. Regardless of the horizontal or vertical installation, the fluid flow must be consistent with the flow arrow on the sensor body. 
4 requirements for the external environment
Sensors should not be installed in places where the temperature changes greatly and within the range of heat radiation of the equipment. If it is necessary to install, there should be insulation and ventilation measures. When installing in a humid, corrosive gas environment, moisture protection and isolation must be done. In addition, because electrical noise can interfere with the correct measurement of the sensor, the installation location should be far away from high-power transformers, motors, and other interference devices.
The construction of the generators is of drip-proof, salient pole rotating field self excitation and constant voltage type. The alternator interior is used with high quality electric magnetic and Electric materials. Stator insulation is class B.
