Water level sensor

• Determines and periodically reports the current water level, sends an alarm signal in case of a sharp change in level. Threshold value for monitoring and alarms is configurable
• Maintenance free (turn on and forgot)
• All-weather performance, IP67
• Sensor based on a pressure measuring technology, that makes him simple and reliable
• Powered by an ER14505 battery (included) rated for 50,000 messages, guaranteeing a minimum of 5 years of operation (one message per hour)

 
Water level sensors are successfully used to control the level in tanks, reservoirs, storm sewer wells, reclamation wells, on embankments, under river bridges and in lowlands. The autonomous design of the sensor allows it to be used in a variety of tasks - smart agriculture, smart city, railways and roads, and so on.
