DP Level Transmitter with Zero Suppression Calibration

Schematic Diagram of a Open Tank DP Level Transmitter with Zero Suppression Calibration

Open Tank DP Level Transmitter with Zero Suppression Calibration

 

Formulas:

Min range = SG x Z + P0

Max range = (SG x Z) + (SG x H)

Example:

If the height of an H is 3.5 meters high and 1.5 meters Z is, in the tank, there is a liquid that has a density of 1 g / cm3 what the calibration range of the transmitter?

SG = 1

Min range = SG x Z + P0

= 1 x 1,5 m + 0
= 1.5 mH 2 O

Max range = (SG x Z) + (SG x H)

= (1 x 1.5) + (1 x 3.5)
= 1.5 + 3.5
= 5 mH2O

The transmitter Range 1.5 to 5 mH2O
