How to calculate the pressure difference in a differential pressure level gauge
Thread Content
Urgent request: How is the pressure difference calculated for a differential pressure transmitter? When the positive pressure chamber and the transmitter are not at the same height.
Density, altitude, gravitational acceleration – calculate it slowly; you haven’t given any specific instructions on how to help me with it
P1-P2=pg(h1-h2). There are too few characters in the mobile phone keyboard; just make do with it!
If they are not at the same height, won’t both the zero point and the range shift? ? Can you use the handheld device to mark it and take a look? Automatically calculated!
△P=ρgh… Give me the formula, without specifying units. What’s the use of a sphere in engineering applications? △P: Unit is kPa; ρ: Unit is grams per cubic centimeter. For engineering calculations, 9.8 m/s² is commonly used; in most areas of China, the actual value of gravitational acceleration is around 9.79XXX. h: Unit is meters. After calculating △P using the actual values, and taking into account factors such as pressure shocks that may affect the safety of the measuring device, the range of the measuring device should be selected by multiplying △P by (1.5±0.1), and then adjusting it to a standard range
