3. Installation and Operating Instructions for Differential Pressure Sensor Water Tank Level Medium Range TECHNOLOGIES Telemetry System ELECTROSENSE This system uses 100mW transceiver modules with frequency hopping technology designed to minimize interference Range is typically 0 5 km urban and up to 5 km rural with a theoretical 24km range Tank Level Pressure Sensor and RF Transmitter Installation e Unscrew the lid on the tank sensor unit and install 4 AA batteries See figure 1 e Lower the pressure sensor and cable through an appropriate hole or opening above the water level in the tank and ensure that the sensor is sitting on the bottom of the tank Excess cable can be pushed into the tank Secure the case to the tank with 2 screws e The transmitter should be mounted as high as possible e If necessary it can be observed that the green LED on the circuit board containing the wireless transmitter inside the unit will light up and flicker when each reading is being transmitted Normally one reading is sent approximately every 10 seconds for the first 3 hrs then one reading every 30 seconds thereafter RF Receiver and Aquagauge Display Unit Installation e Mount the receiver antenna as high as possible and as close to line of sight to the transmitter as practicable e The receiver and display unit have a single power supply Plug in the 120 240V AC to 9V DC power adapter to the display unit and press the power on off button
