Liquid Level Alarm - Solar Powered with SMS


MATelec’s Liquid Level Alarm with SMS features our newly designed ME-Link module, which is a cellular CAT-M1 remote monitoring and control device utilising the 700Mhz frequency for 'best in class' signal strength. The ME-Link reports status information and active alarms from the Liquid Level Alarm. The ME-Link Module can also be used to control external devices with the two onboard relay outputs. Easy to set up SMS commands are used to configure the operation and alarms without the need for any additional software.
