7089 Basic Monitor & Pressure Sensor

The Model 7089 Basic Monitor & Pressure Sensor is a complete, compact, low-cost, single-channel, remote tank monitoring system, with cellular monitor and integral fluid pressure sensor. The system is capable of sensing and reporting tank liquid levels to the Internet (via modern 4G cellular telecommunications) for viewing.

The 7089 Basic Monitor & Pressure Sensor is housed in a durable, compact, UV-protected, sealed plastic case, allowing it to fit in locations where other monitors cannot. A 1½-inch NPT pipe nipple is attached, for convenient attachment to a tank, with the sensor cables extending down through it.

The  7089 Basic Monitor & Pressure Sensor can be fitted to a wide range of tanks, for fluids ranging from oils and lubricants, to fuels, to industrial and agricultural chemicals, to water.  Sensor cables are available in various lengths.

In addition to normal reporting, alerting and alarms, a new feature — “pseudo real time” (PRT) — enables it to report whenever fluid volumes change a certain (user-specified) percent.
