True Airspeeds
-
These true speed indicators are differential pressure indicators that measure the difference between static and total pressure produced by ram air from the pitot. The indicated airspeed can be corrected for changes in altitude by turning the knob to align the outside air temperature with the altitude. The moveable airspeed scale will then show the actual, or true, airspeed.

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.
