Description of Equipment or Protective System:
The Type WLS can consist of two types of sensors; a water level sensor and a multi spot temperature
sensor.
The Type WLS is configurable with respect to dimensions, number of sensors and positioning of
sensors to suit a broad range of applications.
The water level sensor is placed at the end of a flexible stainless steel tube and up to 16 RTDs can be
integrated in the length of the tube. The vertical position of the sensors and the length of the water level
sensing device are variable and can be specified by the user within the limits set out in the datasheet.
There are two versions of the level sensing device:
Type WLS HART version using HART communication technology and being a 2 wire device.
Type WLS MODBUS version utilizing ModBus communication protocol and being a 4 wire device.
If the WLS is ordered without the capacitive level sensor, up to 20 RTDs can be ordered in the flexible
tube. The Type NL sensors are available as: NLI, NLV, or NL-Cryo depending on the specific
application.
