Sommer - Model PTM -Water Level Monitoring Pressure Probe
The PTM– Pressure probe, measures water level and temperature. It offers long-term measurement stability with an extremely high accuracy of 0.05%. Using an SDI-12 interface (analog 4-20mA is optional) makes the integration simple and easy. With a robust stainless steel housing (titanium is optional) and a rugged cable, this sensor is ideal for monitoring water levels in a variety of applications.
