| Open Tank DP Level Transmitter with Zero Suppression Calibration |
Formulas:
Min range = SG x Z + P0
Max range = (SG x Z) + (SG x H)
You can use our instrumentation tools for easy & online calculation of transmitter ranges.CLICK HERE.
Example:
Note:
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
