Description

The Aqua Purometer Kit is designed to provide indication of the degree of contamination in a water system and to provide control and alarm action when the degree of contamination exceeds a pre-set limit. The typical operating range of the system is 0-500 mhos. The system has been designed to provide cell temperature compensation over the broad range of 0 to 100 degrees C. Throughout this range, cell response is corrected to 25 degrees C.

The kit physically consists of the AP-IE PCA, meter, and alarm lamp. Conservative design assumptions for both electronic and mechanical components are the rule throughout.

The kit contains some of the functional elements of cell operation, set point circuits, relay control circuits, measuring meter, and power circuits. The electronic circuits used to accomplish these functions are completely solid state and are mounted on a printed circuit board assembly. The printed circuit board assembly is mounted to the OEM cabinet. This board contains the regulated power supply, system electronics, and the interconnection terminal block.

The screw-in cell has a 3/4-inch or 1-inch NPT screw thread and mounts into a tee or tank wall fitting. All cells are factory calibrated and are purchased separately.
