Propane Fuel Sensor (SN-110)
The wind machine station is a thing
As you can see it works
The propane sensor fits onto most propane (LPG) tanks and records fill level from 20-80%. The sensor fits 'remote ready' tank dials and plugs into the Altrac Wind Machine station at the base of the wind machine through the accessory port.
If you need a new dial, contact Altrac directly to obtain a dial replacement guide. Replacing dials takes approximately 5-10 minutes and costs ~$10.
