Absolute Unvented Reference Hydrostatic Liquid Level Sensors

Non-vented absolute range hydrostatic level sensors for measuring liquid level where it is not possible or practical to connect a vented gauge reference.

These sensors have a fixed pressure reference and therefore level readings are not self-compensated for changes in barometric pressure.

Fixed reference level sensors are typically used in underwater vessels where it is impractical to run a vent tube to the surface.

It is necessary particular with low range depth measurement to also measure the barometric pressure separately to adjust the reading to the correct depth.
