What are the characteristics of china Electromagnetic Open Channel Flowmeter? 1. It is a simple, portable open-circuit system with a built in voltage detector. 2. The open-circuit flowmeter is powered by a 9-volt battery (the battery is not included with the unit). 3. It measures the electric field of a fixed source of magnetic field. 4.. 5. The open-circuit flowmeter can be powered by a variety of current sources and the flowmeter is not required to draw The open-circuit flowmeter is powered by a 9-volt battery (the battery is not included with the unit). 3.. 4. What are china Electromagnetic Open Channel Flowmeter?china Electromagnetic Open Channel Flowmeter is a flow meter, which is used to measure the flow or the electric current flowing in the circuit. It is used to measure the flow or the electrical current in the circuit or in the circuit connected to the outside of the circuit. The flowmeter is installed with a probe connected to the outside of the circuit to measure the flow of water in the circuit. The flowmeter is also used to measure the flow of electricity in the circuit or in the circuit connected to the outside of the can see the flowmeter on the picture belowWhat is the difference between the different types of open channel flowmeter?The type of open channel flowmeter depends on the type of circuit you are measuring, the type of equipment you are using, the type of fluid you are measuring, and the length of the flow.
