Oval Gear Flowmeters
-
Titan’s oval gear (OG) range of flow meters operate on the basic positive displacement technique in that they take a discrete volume of liquid and pass it from the inlet to the outlet without loss or slippage. By nature these devices perform better at higher viscosities as the increasing fluid thickness reduces the leakage rate even further and extends the useful operating range to lower flow rates. The oval gear design allows these flowmeters to operate with a very low differential pressure, only millimetres of head in some cases.

Multivariable Transmitters
-
The Multivariable transmitter measures and calculates the mass flow as a function of differential pressure DP as well as absolute pressure and the temperature. Therefore it should be used whenever DP flow measurement needs a compensation of temperature and pressure. The main advantage is to have just one single device in the field instead of several transmitters and a mass flow calculator.
