How much is a 2 inch water flow meter? And which type of water flow meter should you buy? We all analyze.
Commonly used 2 inch water flow meters mainly include electromagnetic, ultrasonic and mechanical water meters.
Here, we mainly introduce these three types of water flow meters.
2 inch Water Flow Meter types
2 inch magnetic flow meter
Magnetic Water Flow Meter is an electromagnetic flowmeter used to measure conductive fluids. Conductive liquids such as drinking water, sewage, wastewater, seawater, ammonia, cement slurry, etc.
Magnetic Water Flowmeters provide highly accurate flow measurements for a wide variety of conductive fluid applications. Magnetic Water Flow Meter is a volumetric flow meter that measures liquids or liquid slurries that have a minimum conductivity of 5 µS/cm. Based on Faraday’s law of electromagnetic induction. Magnetic Water Flow Meter is ideal for wastewater applications or any dirty liquid which is conductive or water-based. It is widely used in water treatment, environmental protection sewage measurement and control, papermaking, and other industrial and agricultural production processes for flow measurement and control.
