Device for testing and calibration float level gauges are free pulley (3), suspended on a cable (S2) check level gauge (SI), solid roller (8), container (5), liquid filled (6), which is immersed float (S3) by surface measure, pegged to the axis of the free pulleys (3, 4), and devices for measuring the length of the cable (1) with traction device (2). Container (5) can be in weight (7). Method of testing and calibration float level gauges are carried out by the cable (S2) level gauge (SI) creates free pulley (3) and float (S3) hangs down from the end of the cable is attached to the axis of the free pulleys (3, 4) and partially immersed in a container (5) with liquid (6), the free end of the cable passed through a fixed pulley (8) is attached to a device for measuring the length of the cable (1) with traction device (2). Then lowering, respectively. increase of the free liquid level in the tank simulates or releasing certain length of cable (S2), which correspond to the level and whose precise value is measured by a device for measuring the length of the cable (1) and this was finally compared with the difference of level meter indications tested. |
