Gas Purged Pressure Gauge

Science / Tides and Currents / Gas Purged Pressure Gauge: A type of water level gauge in which gas, usually nitrogen, is emitted from a submerged orifice at a constant rate. Fluctuations in hydrostatic pressure due to changes in water level modify the recorded emission rate. Same as bubbler tide gauge.
