Many people may have such doubts, can flow meters be used for flow regulation and control?
A flowmeter is a type of flow meter, which has many types. Flow meters themselves do not have the function of regulating flow, but can provide control and adjustment information through signal feedback.
Flow meters can output 4-20mA current signals. In flow regulation and control systems, the main function of flow meters is to convert the measured flow into current signals and transmit them to the control system. Through the control system, valves can be opened and closed to achieve flow regulation and control.
To achieve flow regulation control, there must be three types of equipment on site: intelligent flow meters, flow control systems, and regulating valves or valves. If there is no control system and valves on site, we need to equip flow quantitative controllers and electric regulating valves to meet the requirements. The flowmeter serves as a measuring device, measuring the flow rate on site and converting it into a 4-20mA signal, which is then transmitted to the control system. We need to set the required flow rate on site in the control system. When the flow rate reaches the set value, the control system sends the signal to the regulating valve, which opens or closes the valve. This is how the entire system works.
So, flow meters can really achieve flow regulation and control, and they are accurate and efficient.
