PURPOSE:To control the flow of fluid positively without making sacrifice of detection performance even upon inclination of a vessel while reducing the manufacturing cost by inserting the sensor body and the flow-in/flow-out ports of fluid, closely to each other, into a fixing flange formed at the end of the body of vessel. CONSTITUTION:A fixing hole 3 is made through the top plate 2 of a vessel 1 and a projection having a threaded hole is projected. A sensor 6 comprises a sensor body 7 housing a machine for detecting the liquid level, and a fixing flange 8 having a hole being fitted to the projection and a liquid flow-in/flow-out port 10 being inserted with a pipe 12. The flange 8 is provided, on the rear thereof, with an O-ring 13 for sustaining the airtightness. Since the sensor body 7 and the flow-in/flow-out port 10 are disposed closely in the center, the sensor 6 indicates a good liquid level detection value constantly even if the vessel 1 inclines in the way of transfer and thereby the flow of fluid can be controlled positively. Furthermore, the manufacturing cost is reduced by arranging the flange 8 collectively. |
