Product Details

Product Description:

QX-LWGY-B typeSimple plug-in liquid turbine flowmeterIt is a precision flow measurement instrument, which can be divided into tangential sensors and axial sensors depending on the type of sensor. The plug-in turbine flowmeter sensor (referred to as the sensor) is matched with the display instrument to form an plug-in turbine flowmeter, which can be widely used for measuring the flow rate and total amount of large diameter pipeline source water, circulating water, purified water and other liquids.

1、 Features of plug-in liquid turbine flowmeter sensor:

1. Characteristics of tangential sensors:
Strong anti impurity ability, the tangential impeller can release suspended debris in the fluid at any time during rotation, so that it does not wrap around the blades of the tangential impeller.
Strong resistance to electromagnetic interference and vibration.
The structure and principle of sensors and display instruments are very simple and intuitive, making it particularly easy for users to master their usage and maintenance techniques.
After replacing the impeller and bearings, the instrument coefficient remains unchanged.
Wide flow range, low lower limit flow rate.
The complete flow meter has a small measurement error for the total amount of fluid.
Almost no pressure loss, saving power and electricity consumption.
The sensor can be installed outdoors, and the entire sensor can be submerged in water for a long time.
Sensors with shut-off valves do not require shut-off during installation and disassembly.
Horizontal, vertical, and inclined pipelines can all be used.
The purchase, installation, and decoration costs of complete flow meters are low. 、

2. Characteristics of axial sensors:
