Mode code:

Mounting size:


Temp.range:-20°C~ +100°C
Pressure:0.1~0.15MPa
Installation instructions and accessories:
Based on the center distance (E) of the selected specification, machine two mounting holes. For example, if the tank wall thickness is ≤10mm, the center hole for the two mounting screws should be 11mm; if the tank wall thickness is >10mm, the threaded hole for the two mounting screws should be M10. The flat surfaces of both types of holes need to be treated to prevent oil leakage after installation. Level gauge accessories: two nuts, two washers, and two sealing flat washers,which are all provided by our company.
Ordering Information:
Select the appropriate model based on the tank level. For a level gauge without a thermometer and with a screw hole center distance of 250mm, the model number is YWZ-250; for a level gauge with a thermometer, the model number is YWZ-250T. Note: Do not allow the surface of this product to come into contact with banana oil; when used with water-glycol, a thermometer cannot be included.
