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.

Mass Burette Flow Detector
FX-1100 Series
The FX-1100 Series Mass Burette Flow Detector takes the position of the fluid surface inside the burette as the head pressure using the differential pressure detector attached at the bottom and directly measures the flow of fluid as a mass based on changes in this pressure. It does not require calculation correction of temperature and specific gravity, and has many advantages such as high accuracy and extremely less affected by air bubbles, which enable to measure fuel consumption in the tests such as chassis dynamometer and engine bench. The 3 models are available according to the measurement range and application.
