Precautions for installation of liquid intelligent turbine flowmeter:

Sensors can be installed horizontally or vertically, and the fluid direction must be upward when installed vertically. The liquid should fill the pipeline without any bubbles. During installation, the direction of liquid flow should be aligned with the direction indicated by the arrow on the sensor housing. The upstream end of the sensor should have a straight pipe section at least 20 times the nominal diameter, and the downstream end should have a straight pipe section at least 5 times the nominal diameter. The inner wall should be smooth and clean, without defects such as dents, scale, and peeling. The axis of the sensor's pipeline should be aligned with the axis of the adjacent pipeline, and the gasket used for connecting and sealing should not penetrate deep into the interior of the pipeline.

Sensors should be kept away from external electric and magnetic fields, and effective shielding measures should be taken if necessary to avoid external interference.

In order to avoid affecting the normal transportation of liquids during maintenance, it is recommended to install a bypass pipeline at the installation location of the sensor.

When installing sensors outdoors, please ensure that the amplifier and plug are waterproofed. The wiring between the sensor and the display instrument is shown in Figure 4.

When there are impurities in the fluid, a filter should be installed, and the mesh size of the filter should be determined according to the flow rate of impurities, generally ranging from 20 to 60 mesh. When there is free gas mixed in the fluid, a deaerator should be installed. The entire pipeline system should be well sealed.

Users should fully understand the corrosion situation of the tested medium and strictly prevent the sensor from being corroded.

Usage and adjustment of liquid intelligent turbine flowmeter:

When using, the tested liquid should be kept clean and free of impurities such as fibers and particles.

When starting to use the sensor, it should be slowly filled with liquid before opening the outlet valve. It is strictly prohibited for the sensor to be impacted by high-speed fluid when it is in a liquid free state.

The maintenance cycle of 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 sensor is not in use, the internal liquid should be cleaned 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.

◆ The filter used should be cleaned regularly. When not in use, the liquid inside should be cleaned. Like the sensor, it should be sealed with a dust boot and stored in a dry place.

The transmission cable of the sensor can be laid overhead or buried underground (iron pipes should be covered when buried underground)

Before installing the sensor, connect the wires to the display instrument or oscilloscope, turn on the power, 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.
