Tank/Reservoir Level Gauges

To accurately monitor the oil level in your tanks and reservoirs, choose Donaldson level gauges. Three models indicate oil level and temperature, 35º to 210ºF (30º to 90ºC). Two models indicate oil level only. Transparent lens material is protected by metal bar with BunaN seals. Maximum working pressure for all models is 14.5 psi / 1 bar / 100 kPa for pressurized tanks. Recommended bolt tightening torque is 10 lbs-ft, with inside nut for tightening directly on the tank. Suggested mounting hole diameter: 11mm or 13mm.
