<p>A device for measuring the level of admission in a recipient for flowing substances, for example, fluids, comprising a capacitive Teflon-coated probe connected to an electric processing circuit (18) and inserted into the recipient (22) said probe consisting of at least two relatively isolated measuring pipe-section (1, 2) in line with one another and one of which serves to fix a reference value regarding the properties and nature of the fluid, whereas the other section concerns the measurement of the fluid level, said probe being enveloped by a grounded tube (27) connected with the wall of the recipient, whereas the top of said probe is mounted in a housing by means of a sealing being formed by at least one annular filling body (12) between a widened part of a bore in said housing and the coating of the probe, whilst pressing means impose an axial load on the or each annular body, and wherein the electric processing circuitry (18) includes communicating means for simultaneously energizing one measuring section of the probe and grounding the other measuring section and conversely. </p> |
