The liquid turbine flow meter is used to measure the flow rate of low viscosity liquid in closed pipe ranging from DN4 to DN200 mm. With the advantages of high accuracy, good repeatability, simple structure, small pressure loss and convenient maintenance, the turbine flowmeter is widely applied in the petroleum, chemical, metallurgy, water supply, paper and other industries.

Feature

Selected 304 stainless steel material, is non-conductive stainless steel body, can isolate the external magnetic field.
Precision milled impeller molded in one piece, CNC precision machining, more accurate data.
Blocked circuit board upgraded with intelligent algorithm, effectively filtering stray waves.
Metal electrical interface effectively isolates water and dust, no fear of wind and rain.

Application

Tips: Turbine Flow Meter Working Principle

When the fluid passes through the sensor of the turbine flow meter through the pipe, the impeller in the sensor rotates under the impulse of the fluid. The impeller changes the magneto-resistance in the magneto-electric induction system periodically, so that the magnetic flux through the coil changes periodically and produces the electric pulse signal. After the circuit amplification processing, the output has a certain amplitude of the continuous rectangular pulse, the field can directly display the measured flow, or the signal can be transmitted to the display instrument or communication output.

Precautions for turbine flowmeter installation and use

The turbine flow meter should be away from external electric and magnetic fields.
The upstream end of the flowmeter is recommended to keep at least 10D straight pipe segment (D is the nominal diameter of the pipeline), and the downstream end is not less than 5D straight pipe segment.
When there are impurities in the fluid, filter should be added.
At the beginning of the use of the turbine flowmeter, the flow sensor should be slowly filled with liquid, and then the outlet valve should be opened. It is strictly prohibited for the sensor to be impacted by high-speed fluid when it is in the state of no liquid.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
