ABSTRACT:
An apparatus for surveying the pressure of fluids housed in tanks or flowing through ducts comprises a device (100), an envelope (1) with axial symmetry which forms the external covering of the device (100), said envelope (1) being kept in distal position with respect to a connecting body (2) by a counter spring (3); the envelope (1) axially slides with respect to the body (2) to allow the commutation of the apparatus (100) from a non-active to an active condition; the commutation of the device (100) is due to an external force (F).
