Magnetic Open Channel Flowmeter
The AFTLDM-17 electromagnetic open channel measurement system is an open channel measurement flow system that is composed of a flow indicator, a flow meter, and a liquid level meter. Open channel flow measurement system composed of flow indicator, flow meter, and liquid level meter to measure flow by velocity area method.
Key Benefits
- The measurement is not affected by floating objects in the water, sediment content, water level changes, and temperature
- The flow rate sensor is easy to install and does not produce resistance to water flow
- The standard section can be installed directly without modification, and the installation and construction are difficult and low cost
- mmune to the effects of temperature, pressure, density and viscosity of the fluid.
- It has the function of permanent data storage, which can save the set parameters and flow value in the case of long-term power failure
Product Description
The full channel width measurement and control integrated measurement system uses the flow-area method measurement principle as the basic measurement method. It is composed of a full channel width electromagnetic flow sensor, a liquid level sensor and an intelligent converter. Its working principle is to measure the full channel width electromagnetic flow sensor. The obtained average flow velocity of the section is combined with the real-time water level measured by the liquid level gauge to calculate the section area. The average flow velocity of the section is multiplied by the section area to obtain the channel flow. Liquid level gauges of different principles and forms can be used to measure the water level of the section. The liquid level gauges are generally ultrasonic level gauges, pressure level gauges, etc.
