ERECTA SWITCH® by Compac Engineering

Diesel Day Tank Level Switches

Low-fuel alarms and fill control for generator day tanks, in Acetal for diesel compatibility — with side-mount and extended-stem options for skid-framed tanks that have no vertical access.

The problem

A generator day tank is a hard place to put a level switch. The tank is usually horizontal and sits inside a steel skid frame, so there is no clearance above it for a top-mounted probe. The fluid is diesel, which rules out some plastics. And the signal normally has to drive an alarm lamp or a panel input directly, not just close a dry contact.

Application examples

Horizontal Fuel Day Tank — Low Level Alarm

A generator packager uses horizontal cylindrical day tanks where there's no vertical access through the top — the tank sits inside a steel skid frame with no room for a top-mounted switch. A side-mounted 10-788-AC installs through the tank end wall at the low-level alarm height. Acetal construction resists diesel fuel. The relay housing accepts an optional solid state relay to drive an alarm panel directly without a separate relay enclosure.

Diesel Generator Fuel Tank — Low Level Alarm

A standby generator manufacturer needs a low-fuel alarm in their day tank. Diesel fuel requires Acetal construction for chemical compatibility. The angle connector routes the lead wire away from the tank wall in a tight engine compartment. The switch activates a warning lamp and audible alarm on the generator control panel. Relay housing protects the connection in an outdoor enclosure.

Material selection

Every ERECTA SWITCH configuration is available in three materials. For this application the usual specification is Acetal (AC).
