WLS – Water Level Sensor 

The capacitive Water Level Sensor (WLS) continuously measures free water level below the oil surface and provides input for on-line net inventory. The sensor is integrated with the Multiple Spot Thermometer (MST).

The WLS is welded to the MST to get a hermetic design and it has no moving parts.

The WLS output is an analog 4-20 mA or digital HART signal, which is connected directly to a radar gauge.

There is a PT-100 temperature sensor inside the probe, allowing measurements at low levels.

The WLS is designed for difficult applications in corrosive environments and is detachable for repair.

The open model WLS is suitable for crude oil applications and the closed model is suitable for lighter fuels such as diesel etc.

A junction box can be integrated with the WLS.
