Pressure/ Vacuum Sensors
-
There are three different types of pressures that can be measured using Premier Electrosystems' Pressure Sensors: Gauge, Absolute, and Differential. Gauge pressure is the pressure measured relative to the ambient atmospheric pressure.A typical application for a gauge pressure sensor is to measure liquid levels in a vented tank using the difference in hydrostatic pressure and ambient atmospheric pressure. Absolute pressure sensors will give the result relative to zero (a perfect vacuum). This is useful in applications where there is a direct effect of altitude on the pressure being measured. Differential pressure sensors measure the difference in pressure between two points. Differential pressure sensors are often used to monitor airflow in HVAC applications.

Differential Pressure (Density)
VEGADIF

In density measurement of liquids with differential pressure, two pressure measuring points are mounted at a fixed distance from each other. There are thus two different pressures acting on the system. The differential pressure transducer calculates the density of the medium from the resulting pressure difference.

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.
