Product Description


The Watchman TMS300 CS tank monitor continually monitors every tank in your business. Developed by Kingspan Sensor, the TMS300 CS gives you full transparency on the performance of your tank population. The TMS300 CS Multi-tank has been designed to work with the Watchman LT tank monitoring solution. The device can act as both local and remote monitor giving tank information on site, in a local office via a LAN and remotely using the app and website. The device can monitor up to 18 tanks both wirelessly and using fixed wired sensors. Scheduled and alert driven information is sent to the Kingspan Smart Monitoring data hosted platform, Connect Sensor. Connect Sensor is capable of hosting real time information from the TMS300 CS Multi-tank as well as the Watchman LT. Tank levels from each TMS300 CS can then be shown on the Connect Sensor platform available on Android and iOS.
