Smartswitch are please to announce their new easy to read Blue Tank Monitor system. The TC-8000 is able to monitor and control up to 8 tanks, including fuel, water, black, or grey. You can set various alarm levels, high for black and low for fuel, turn on water makers, deactivate the toilet when the black tank is full, and monitor whether sea-cocks are open when trying to pump. Easy to install, can measure odd shape tanks, and runs on a simple 2 wire network cable. Other options are available. www.smartswitch.co.nz
