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.

Describle:
PP plastic filters is developed and designed for chemical industry. It is an excellent economic and practical anticorrosive filter which is widely used in solid-liquid separation of corrosive materials of acid and alkali. The whole plastic cylinder and its accessories are made of pvdf, pph, ppr and other anticorrosive plastic materials to realize the contact between non-metal parts and materials, which can be competent for high temperature, high concentration hydrochloric acid, sulfuric acid, etc. aqua regia and other strong acid strong base liquid filtration and most of the chemical liquid filtration. The filters are fast open, easy to maintain, easy to disassemble. The bottom of the cylinder is designed with a clever slope, no residual fluid after filtration. The integral molding injection molding process makes the cylinder without any soldering interface and solder joint, and the inner surface is smooth without dead angle. The plastic anticorrosive filter is widely used in chemical industry.
1.The Filter Material inlet adopts the jacking tortoise shell design, the liquid flow is more unobstructed and the liquid accumulation.
2. Top cover adopts the quick opening way, the maintenance is convenient and easy to disassemble, and it is equipped with 6 sus316 flange bolt rings to protect the pressure.
3. The bottom of the sealing filter adopts slope design, no residual liquid after filtering, to avoid material waste .
4. The barrel body ,basket, and the filter bag ring is made of high temperature modified polypropylene (ppr/pph) or pvdf anticorrosive material.
5. The cylinder body has no welding interface and weld, and the smooth and beautiful.
6. The sealing ring is made of fluorine rubber material. Excellent corrosion resistance.
7. The flange bolt hole spacing of inlet and outlet has multi-functions, which can be matched with national standard, American standard, day standard, German standard flange.
8. The mounting square base to enhance the safety and stability of the filter, easy to be fixed in different demand situations .
