Pressure measuring instrument. |
摘要 |
<p>A pressure measuring instrument suitable for immersion in water to measure wave and tidal pressures comprises a cylindrical body (1) within which is a compliance chamber (12) communicating with the external pressure through a restrictor (14), the system being chosen to have a time constant preferably in the range 60-300 seconds. Transducers (18, 16) respectively measure the differential pressure between the complaince chamber (12) and the exterior, and the pressure within the compliance chamber, giving measures of wave pressure and tidal pressure.</p> |
