Differential pressure level range
Thread Content
Why is the difference in densities of the two media used to calculate the range for a differential pressure transmitter operating with these two media?
The range of a differential pressure transmitter is the static pressure of the medium on the high and low pressure sides of the transmitter, which is given by the formula Hρg, where ρ represents the density of the medium; therefore, it is necessary to use the densities of both types of media for calculation.
