1. How to maintain the turbine flowmeter sensor

1. When using, the measured medium should be kept clean and free of impurities such as fibers and particles.

2、 When starting to use a turbine flowmeter, the sensor should be slowly filled with medium before opening the outlet valve. It is strictly prohibited for the sensor to be impacted by high-speed fluid when it is in a state of no medium.

3、 The maintenance cycle for turbine flow sensors is generally six months. During maintenance and cleaning, please be careful not to damage the parts inside the measuring chamber, especially the impeller. Please pay attention to the position relationship between the guide components and the impeller during assembly.

4、 When the turbine flow sensor is not in use, the internal medium should be cleaned, dried, and protective covers should be added at both ends of the sensor to prevent dust and dirt from entering, and then stored in a dry place.

5、 The matched filter should be cleaned regularly. When not in use, the internal media should be cleaned. Like the sensor for pulse detection, it should be sealed with a dust boot and stored in a dry place.

2. How to wire turbine flowmeter

Turbine flow sensor/transmitter (LWGY - □ N type Huiquqing, LWGY - □ A type) 1. Basic LWGY - □ N type "24V+" (red wire) connected to DC24V positive terminal; Connect the "power supply -" (white wire) to the negative terminal of DC24V; Pulse "(yellow line in the foreland) is connected to the pulse input terminal of the secondary meter. 2. Explosion proof LWGY - □ N type, as shown in Figure 8. 3. LWGY - □ A type, as shown in Figure 9.

3. Science popularization: Precautions for installation of turbine flowmeter

Turbine flowmeter (impeller flowmeter) is a high-precision instrument that uses turbine rotation for flow measurement. It has the advantages of simple structure, high temperature resistance, and long service life.

1. Installation method: The turbine flowmeter supports three installation methods, which should be selected reasonably according to the working conditions: flange installation: suitable for standard connections in pipeline systems, ensuring that the flange sealing surface is flat and the bolts are evenly tightened to prevent leakage. Threaded installation: Used for small-diameter pipelines (usually below DN50), attention should be paid to thread matching to avoid thread damage caused by violent tightening. Clamp on installation: suitable for temporary measurement or space limited scenarios, ensuring uniform clamping force to prevent sensor displacement.

2. Fluid direction control. Mandatory requirement for liquid measurement: The fluid flow direction must be completely consistent with the arrow direction marked on the sensor housing. Reverse flow can cause the turbine to reverse, leading to measurement errors and even mechanical damage. Gas measurement suggestion: Although there is no mandatory requirement, maintaining consistent flow direction can reduce turbulence effects and improve measurement stability.

III. Outdoor Installation Protection and Waterproof Treatment: When installing outdoors, the amplifier plug needs to be sealed. It is recommended to use a dedicated waterproof joint (IP65 or above level) with a silicone sealin
