How to determine the pressure before the gravity-driven self-acting control valve
Thread Content
As the title suggests, it is a control valve that relies on gravity for flow; the pressure before the valve is thus determined by the weight of the material itself. If the liquid level of the material in the reactor changes (from a full level to when all the material has been drained), then the weight also changes. In such cases, how should the pressure before the valve be determined?
The changes in pressure before the valve can be determined by monitoring the liquid level of the material inside the reactor in real time. After each discharge, record the liquid level and weight at that time, and then compare them with the liquid level and weight before the next discharge. By calculating the change in the weight of the material, it is possible to determine the change in the pressure upstream of the valve. Instruments such as pressure sensors and level sensors can be used for real-time monitoring. -
