  • Page 21: Principle Of Operation

    1.4 Principle of Operation 1.4.1 Liquid Sensing Figure 3 Liquid Sensor Sensor Body 8990int.fm The sampler is designed for indoor, permanent installation. All controls are located on the front panel. Capped, watertight connectors for interfacing to external devices are located along the left side of the controller. The sampler uses a liquid sensing system to detect the absence or presence of liquid at the peristaltic pump intake.
  • Page 22 Section 1 Page 20 Principle of Operation Intake Tube Pre-Rinse The liquid sensor also rinses the intake tubing with the liquid from the sample source before taking each sample. Upon sample initiation, the pump purges the intake line. The pump then reverses, pulling liquid through the tubing, until it reaches the liquid sensor.
