  • Sensor for remote measurement of fluid depth in environmental monitoring
    Patent number: 10564024
    Abstract: A pneumatic depth sensor system for remotely reporting on a depth of a body of fluid is provided. The system comprises a regulated source of compressed gas, a first pressure sensor upstream from a normally-closed electronic solenoid valve, a second pressure sensor downstream from the electronic solenoid valve and a bubbler outlet downstream from the second pressure sensor, the bubbler outlet for locating at a bottom of the body of fluid, the depth sensor system under control of a microprocessor, the microprocessor in electronic communication with the first and second pressure sensors and the normally-closed electronic solenoid valve, and configured to instruct the normally-closed electronic solenoid valve to be in a fully open position or a fully closed position and to rapidly change position in response to a pressure reading from the second pressure sensor.
