What are the functions of china Electromagnetic Open Channel Flowmeter?The Electromagnetic Open Channel Flowmeter is a simple open circuit flowmeter that measures the flow of current through the circuit. It is used to measure the flow of DC current through an open circuit. circuit, without the need to open the circuit in order to measure the is used to measure the flow of current through a circuit, without the need to open the circuit in order to measure the flow. circuit, without the need to open the circuit in order to measure the flow. circuit, without the need to open the circuit in order to measure the flow. circuit, without the need to open the circuit in order to measure the flow. How do china Electromagnetic Open Channel Flowmeter work?china Electromagnetic Open Channel Flowmeter is made of CNC machined Aluminum. It has a high quality CNC machined finish and a high quality high temperature brushed finish. Both are machined from high quality stainless steel to provide a strong and durable product.china Electromagnetic Open Channel Flowmeter can measure the flow of both water and electricity. It is a self-propelled open-circuit voltage probe which can be used in outdoor applications. It is great in areas such as in homes, cars, offices, factories etc. It is ideal for testing the flow of electricity and water as they are both electrical and china Electromagnetic Open Channel Flowmeter gives you real time data in real time. It will be able to detect the flow of both water and electricity in the air.
