Liquid turbine flowmeters create a pulse signal that is inversely proportional to the flow rate. When the fluid enters the pipeline, the torsional angular velocity of the turbine flowmeter is inversely proportional to the fluid velocity. A turbine is placed in the center of the pipe, and this causes sensing. The magnetic flux in the coil changes. The sensing coil sends the detected magnetic flux cycle change signal to the preamplifier, and also sends the pulse signal to the frequency current conversion circuit to develop and reshape the signal, so that the turbine replacement counter measures the friction torque and Fluid resistance torque tampers. The liquid should be filled with pipes and there should be no bubbles. Liquid turbine blade flowmeter, magnetic lines of force when the combustion turbine flow meter blade cutting fluid generated by the permanent magnet housing, the fluid flow rate through the turbine meter tampering may lose angular velocity, liquid turbine flowmeter converts the signal into an analog pulse The amount of current, for a certain viscosity of the fluid medium, the rotational speed of the turbine meter is detected by a sensing coil mounted outside the housing. Both ends are supported by bearings. It is therefore important to argue that the fluid flow through the pipeline is lost. In the area of ​​non-essential traffic, it further indicates the traffic value at the time of arrival. The feed unit conversion and flow totalizer obtains and discloses the performance of the aggregated flow rate. When the turbine flowmeter is installed, the direction of liquid flow should coincide with the direction of the arrow on the sensor housing indicating the direction of flow. The upstream end of the sensor should have at least 20 times the straight length of the nominal diameter, and the downstream end should be not less than 5 times the straight diameter of the nominal diameter. The inner wall of the sensor should be smooth and clean, there is no dent, the turbine flowmeter fouling and peeling, etc. defect. The shaft axis of the sensor should be aligned with the axis of the adjacent pipe, and the gasket used for the connection seal must not penetrate into the pipe cavity.

Masking Tape
Masking tape is mainly used in electronic, hardware, furniture, handicraft shoes, toys and other industries. Maskingtape is high temperature resistant (60-300 degrees). Masking tape has many colores, can stick to the paper, composite PET, PVC and other materials. Paper masking tape suitable for curved and contoured surface. The thickness of paper masking tape is from 45 to 65 micron, the width is from 12mm to 24mm, the length is 20 to 100 yards. Could make customs masking tape.
