Level, water, temperature – in real time instead of with a dipstick. As FAFNIR’s official sales and service partner for Switzerland, we advise on, install and maintain your tank monitoring system.

Tanks, sumps, dispensers, separators, leak detectors and even the car wash compressors all report to one system. You see everything in one place – on site, and on the go with VISY-Command Web.

The tank monitoring system that brings the sensors together and keeps a constant eye on your tanks.

Measures product, water and temperature – up to 50 times per second.

For above-ground tanks up to 22 m high.

The variant for LPG tanks.
Monitors manhole and dispenser sumps – so nothing collects there unnoticed.

Overfill prevention sensor to WHG – so nothing spills over during filling.

Your tank data in the browser – from the office instead of the manhole. The VISY-Command central unit also passes the data to your POS or ERP.

The display right at the installation.

Central management of multiple stations.

Radio transmission – when pulling cables isn’t an option.

Brings additional signals into the system.

Switches pumps, alarms or other systems – triggered by readings and alerts.
FAFNIR keeps things calm around the tank too:

COMS monitors your oil separator continuously. The sensor in the separator tells the controller how much has built up. Once a value hits the limit, COMS raises the alarm – and we come out. Not before.
Fixed dates: sometimes pointless, sometimes too late.
Call-out exactly when the limit is reached.
TORRIX measures to within ±0.3 mm. Yes, millimetres.
