Details

  1. Liquid Crystal Display: Using dot-matrix display, natural gas flowmeter display bit more, easy to read can directly display the volume of the working state, the flow rate of the total volume flow rate of the standard state, as well as media pressure, temperature and other parameters.
  2. Electrical Interface: Stainless steel interface effectively waterproof and dustproof, to extend the service life of the gas flowmeter measurement.
  3. Exquisite Impeller: Each impeller is carefully polished without burrs, reducing pressure loss.
  4. Flange Material: Made of aluminum alloy, better working performance and high temperature resistance.

Installation Methods

Description 
Ensure that the length of the straight section on the upstream side is at least 3D and that the length of the straight section on the downstream side is at least 2D. See diagram I. (D: nominal diameter of the rotary vortex flowmeter)
Bends: For bends, ensure that the length of the straight section on the upstream side is at least 3D and that the length of the straight section on the downstream side is at least 2D. See diagram II.
Shrinking: For shrinking, ensure that the length of the straight section on the upstream side is at least 3D and that the length of the straight section on the downstream side is at least 2D. See diagram III.
Expansion: For expansion, ensure that the length of the straight section on the upstream side is at least 3D and that the length of the straight section on the downstream side is at least 2D. See diagram I.
Valve: If there is a valve on the upstream side, ensure that the length of the straight section on the upstream side is at least 5D and that the length of the straight section on the downstream side is at least 2D. See V for schematic diagram.


Application

Tips: Natural gas flow meter installation precautions

When installing and using in outdoor, there should be a cover to avoid sun exposure and rain erosion, which will affect the service life of the meter.

Pipeline pressure test, should pay attention to the intelligent flowmeter configured pressure sensor pressure measurement range, in order to avoid overpressure damage to the pressure sensor.

Attention should be paid to the impact of the installation stress, the installation of the flow meter upstream and downstream pipeline should be coaxial, otherwise it will produce shear stress.

Installation of the gas flow meter location should consider the thickness of the sealing gasket, or in the downstream side of the installation of an elastic expansion joint.
Welding slag and other debris in the pipeline should be removed before installing the flowmeter.

When put into operation, should slowly open the gas flow measurement devices upstream and downstream valves, so as not to instantaneous gas flow is too rapid and wash out the starter.

When the flow meter needs to have a signal transmission, should be strictly in accordance with the “electrical performance indicators” requirements to access the external power supply (8 ~ 24) VDC, is strictly prohibited in the signal output, “port” direct access to 220VAC or 380VAC power supply.

Users are not allowed to change the wiring of the explosion-proof system and unscrew each output lead connector arbitrarily. When the flowmeter is running, it is not allowed to open the back cover to change the parameters of the meter, otherwise it will affect the normal work of the flowmeter.
Regularly check the leakage of the gas flow meter flange.

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.
