The Model 612 Seawater Flow Monitor protects main and auxiliary engines by warning of a partial or complete loss of seawater cooling capacity. A sensor probe, mounted in a tee in the intake line, senses water velocity without moving parts. This data is interpreted and displayed in bar graph form by an electronic module in the engine room. Optionally, this same information can be displayed remotely in the wheelhouse, bridge or control room up to 250 feet away. The 10-segment remote bar graph display is ultra blue in color and automatically adjusts its brightness for optimum viewing in all lighting conditions. Remote displays are available in single or dual versions for easy comparison of flow rates. Special stainless steel tees accommodate hoses of 1 to 3 inches inside diameter. Adjustments are provided to optimize the response of the flow monitor for large variable-speed main engines as well as small constant-speed auxiliary engines. Event, alarm and analog outputs may be used for an optional annunciator and/or a data collection system. A fault in the sensor or its cable is automatically detected and causes the display to flash.
Model 612 kit includes Logic Unit/Engine Room Bar Graph Display (above right) and Sensor/Harness assembly (16 feet / 5 meters).
