An assembly is used e.g. with a pump drive motor. A hollow body (1) on an electric cable extending to a circuit breaker (3) has a moving weight located in one of two different positions depending on the slope angle of the meter. - Pref., in the first position the meter is in air while in the second it is in the liquid. A controller (4) switches the breaker to the closed position when the meter is in air. |
