How to maintain the turbine flowmeter?
When maintaining a turbine flowmeter, the following points should be noted:
1. When using, the measured medium should be kept clean and free of impurities such as fibers and particles.
.2. When starting to use the turbine flow sensor, the sensor should be slowly filled with medium before opening the outlet valve (which should be installed at the back of the flowmeter). It is strictly prohibited for the sensor to be impacted by high-speed fluid when it is in a state of no medium.
. 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. 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, it should be added with a dust boot and stored in a dry place. 6. Before installing the sensor, blow or manually turn the impeller to quickly rotate and observe if there is any display. When there is a display, install the sensor. If there is no display, check the relevant parts and eliminate the fault.

2. The difference between turbine flowmeter and intelligent turbine flowmeter
Turbine flowmeter consists of turbine, bearings, preamplifier, and display instrument.
. The principle of a turbine flowmeter is to place a turbine in the center of a pipeline, supported by bearings at both ends. When the fluid passes through the pipeline, it impacts the turbine blades, generating a driving torque for the turbine, which overcomes the friction torque and fluid resistance torque to produce rotation. Within a certain flow range, for a certain viscosity of the fluid medium, the rotational angular velocity of the turbine is proportional to the fluid flow velocity. Therefore, the fluid flow velocity can be obtained from the rotational angular velocity of the turbine, and the fluid flow rate through the pipeline can be calculated. The rotational speed of the turbine is detected by a sensing coil installed outside the casing. When the turbine blades cut the magnetic field lines generated by the permanent magnetic steel inside the casing, it will cause changes in the magnetic flux in the sensing coil. The sensing coil sends the detected periodic change signal of the magnetic flux to the preamplifier, which detects the magnetic flux. Amplify and shape the signal, Generate a pulse signal proportional to the flow rate, send it to the unit conversion and flow accumulation circuit to obtain and display the accumulated flow value; At the same time, the pulse signal is also sent to the fre
