Abstract

PURPOSE: To make it possible to perform the measurement with a simple construction and a high accuracy and to automatically control a pump for supplying concrete or the like by providing an electrical circuit having contacts to be closed when the detecting wire provided with a detecting weight at its leading end is relaxed and an indicator at the main body of the device.
CONSTITUTION: A piano wire as a detecting wire 3 is suspended down from the main body 1 of a measuring machine provided on the ground at the upper part of a vertical hole 1 or a groove, and a detecting plate 4 is fitted to the leading end of the piano wire. The upper part of the piano wire 3 is engaged successively with four pulleys 5W8 and turns its direction, and the terminal end of the piano wire 3 is taken up to a take-up reel 9. Particularly, in the second pulley 6 the piano wire 3 is engaged therewise so that the piano wire 3 makes a U-turn, and a bar-like magnet 10 is fitted to the frame of the pulley 6. A coil spring 12 is extended between the end of the magnet 10 and the wall 11 to affored tension thereto. Several lead switches whose contacts are opened or closed by a magnetic force are provided in the vicinity of the shifting position of the magnet 10. In this manner, the measurement can be performed with a simple construction and a good accuracy.
