The plug-in water flow meter is a corrosion-resistant all stainless steel ABS full mold production probe with a simple and sturdy structure, no moving parts, long service life, small size, light weight, easy installation, and low maintenance; The ability to install and disassemble without interruption brings convenience to users' maintenance. Compared to general electromagnetic flow meters, it has lower manufacturing and installation costs, making it particularly suitable for flow measurement in large and medium diameter pipelines.

●working principle

The measurement principle is Faraday's law of electromagnetic induction. The main components of the plug-in water flow meter sensor are the measuring tube, electrode, excitation coil, iron core, and magnetic yoke housing. Mainly used to measure the volumetric flow rate of conductive liquids and slurries in closed pipelines. Including highly corrosive liquids such as acids, alkalis, salts, etc.

●application

Insertion type water flow meters are used to measure the flow rate of conductive fluids in sectors such as tap water, steel, petroleum, chemical, power, industry, and water conservancy. They can also measure corrosive conductive liquids such as acids, alkalis, and salts. Insertion type electromagnetic flow meters are widely used in industries such as petroleum, chemical, metallurgical, textile, food, pharmaceutical, papermaking, as well as environmental protection, municipal management, water conservancy construction, etc.

●install

The upstream straight pipe section for sensor installation shall not be less than 5D (D: pipe diameter), and the downstream straight pipe section shall not be less than 2D
Installation method:
（1） Vertical installation, the sensor should be inserted into the pipeline at an angle of less than 5 ° to the vertical diameter of the pipeline section, suitable for measuring clean media with low pipeline vibration.
（2） Tilted installation, with the axis of the sensor at a 45 ° angle to the axis of the measured pipeline, is suitable for measuring the flow rate of liquids with large diameters and other impurities in the measuring medium. This installation method has low water resistance and should not be tangled.
There are two methods for inserting sensors: one is to insert them into the central axis of the measured pipeline, and the other is to insert them into the 0.25D position on the inner wall of the pipeline.

●Precautions

1. Clean the welding slag and burrs on the installation base of the tested tube.
2. Close the upstream flow control valve or use low-pressure water supply.
3. Install the DN50 ball valve onto the mounting base. Pay attention to the long cavity of the ball valve facing upwards, check if the ball valve can be fully opened and closed, and install the clamping thread seat, clamping nut, and rubber sealing ring onto the ball valve. Loosen the positioning nut. Insert the sensor into the measured pipeline through a ball valve, while paying attention to the direction of the sensor indicator rod pointing in the same direction as the fluid flow. Ordering Notice:
Please specify the name of the tested medium, working pressure, medium temperature, flow rate (velocity) range, pipeline diameter, and the condition of the tested pipeline network when shipping.
