TEMPERATURE AND PRESSURE COMPENSATING GAS TURBINE FLOW METER

摘要

A temperature and pressure correction gas turbine flow meter is provided to improve an explosion proof function by hermetically sealing a cable connecting a temperature sensor and a pressure sensor. A temperature and pressure correction gas turbine flow meter comprises a housing(10), a turbine(20), a pick-off sensor(40), a pressure sensor(30), a temperature sensor(50), a controller(60), and an output unit(70). The housing comprises a flow safety bolt(12) and a gas discharge unit(13). The flow safety bolt makes the gas flow stable by minimizing the pulsating. The pick-off sensor senses the pulse generated with a magnet(23) according to the rotation of the turbine. The controller is installed at the upper part of the outer side of the housing. The controller calculates the gas flow rate using the sensed pulse. The controller comprises a coupling unit(61) and a connection unit(62). The inside of the connection unit is hollow. The connection unit is connected to the controller with the cable admitted to inside.
