Control valves allow for quantitative control
Thread Content
How can I add a fixed amount now? How can this be achieved without a DCS, just using a valve on-site? For example, add 1000 kilograms of water and turn it off once the weight is reached.
First, you need a flow meter or weighing device to measure these 1000 kilograms of water; having a gauge will make it easy to control.
Valves alone are not enough; weighing devices or other equipment such as tank level sensors are required. When used together, it is possible to implement this in a system. If you don’t understand, contact me and I’ll explain it to you slowly: lol
The hourly flow rate of the valve is fixed. For example, if 1000 kilograms have been used up and the valve is opened to add another 1000 kilograms, or if water is continuously added to a tank or basin to keep its volume at around 1000 kilograms,
Adding a flow meter and a dosing controller will do the trick
One flow meter, one dosing controller (are there any specific models you can recommend?), and one valve (a on/off valve or a control valve?) ), thank you
It is a requirement of the batch processing process: for example, 1000 kilograms are added to this batch and then adding stops, with further addition taking place only when the next batch is produced. Thank you
A liquid turbine flow meter with pulse output, a quantitative controller with an LCD display, and ordinary solenoid valves can be used for the valves.
It is best not to use a control valve; a solenoid valve will suffice, but a flow meter and controller need to be added
Refer to Floor 5; use a solenoid valve to handle it
