Model TBZ Series
For TBZ series, there are models that have temperature / pressure compensation function. This function is to convert measured actual gas flow to gas flow at certain temperature and / or pressure condition for display, as gas volume changes by variation of temperature and pressure. The relationship between TBZ model and temperature / pressure compensation function is as the following table.
Normally, temperature / pressure condition at which measured actual gas flow is compensated will be Temperature 0°C and Pressure 1 atm (1 atmospheric pressure). However, other value could be set in case it is requested (There are condition to select the value).
Also, at the time of placing order of TBZ series please kindly select direction of flow from the following table.
