Detail

LCD display or 180° rotating head can display instantaneous flow rate, totalized flow rate can be shared on the same screen.
Gas flow meter adopts MEMS chip, high precision, low power consumption, no temperature and pressure compensation.
Battery / power supply dual power supply, can use 4 AA batteries or external adapted power supply.

Accessories (optional)

Note: The optional miniUSB cable is used for the connection to external power supply and RS485 communication.

Application

Tips: Digital gas flow detector installation

The gas flow meter is preferably installed horizontally. Flow direction should be the same as the direction of the arrow mark on the meter body. If there may be particles or debris in the fluid, a filter is strongly recommended to be installed upstream of the meter.

Please follow the below steps to complete the installation:

Check if the meter is complete, no visual damage first.
Before installation, make sure that there is no debris or particles in the pipe.
During installation, it is recommended to first install the inlet of the flow meter and then the outlet. To ensure the accuracy of measurement, the straight pipe length should be remained enough at the installation site of flow meter, upstream no less than 10 times DN and downstream no less than 5 times DN.
Make sure all the wire connections of the flow meter is correct including the wires for LCD, input/output and communication.
Turn on the power supply, and ensure that the LCD works properly.
Slowly turn on the valve of the pipeline, and then the flow meter starts to measure the gas flow in the pipeline.

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.
