VL 255/E PM

VL 255/E PM

An underpressure leak detector with extended electronic functions (/E) in weatherproof design (P) and digital pressure indication (M) for flat bottom tanks (bulk storage tanks).

A sensor in the suction line detects appearing liquids and triggers the alarm. Any alarm, either caused by a pressure drop or caused by detecting liquid at the sensor will result in shut down of the vacuum pump and closing of the solenoid valves in the suction- and measuring line. The leak detector VL 255/E PM is therefore particular suitable for the control of flat bottom tanks where aggressive liquids are stored.

This leak detector is resistant to an overpressure up to 5 bar, to cover the overpressure, which may occur in case of a leak in the upper bottom.

Every leak in one of the walls will be indicated by an optical and audible alarm before liquid enters the environment.
