Abstract
In at least some embodiments, a pressure sensor configuration includes a pressure sensor and a switchable valve coupled to the pressure sensor. The switchable valve enables the pressure sensor to measure pressure at multiple ports of a pressurized tank.
Claims22
A pressure sensor configuration, comprising:
- a pressure sensor;
- and
- a switchable valve coupled to the pressure sensor, the switchable valve enabling the pressure sensor to measure pressure at multiple ports of a pressurized tank.
A remote telemetry unit (RTU), comprising:
- a pressure sensor;
- and
- a solenoid valve coupled to the pressure sensor, wherein the RTU operates the solenoid valve in conjunction with measurements of the pressure sensor to determine a differential pressure of a pressurized tank.
A method, comprising:
- receiving, by a switchable pressure sensor (SPS) unit, a first measurement from a pressure sensor while connected to a first pressure pipe connection;
- receiving, by the SPS unit, a second measurement from the pressure sensor while connected to a second pressure pipe connection;
- and
- calculating a differential pressure based on the first and second measurements.
