Kind Code:
A
Abstract:
To provide a lubricant flow sensor that can measure a flow rate by restraining a back pressure to a low level, has high durability, and prevents malfunction from occurring easily even if a lubricant discharge line having a low pressure of lubricant is provided.SOLUTION: A lubricant flow sensor 70 includes: a horizontal pipeline 72; a weir 74, and a level sensor 76. The horizontal pipeline 72 includes a lubricant discharge line 28d in which lubricant O flows horizontally. The weir 74 includes a lower small-flow-rate opening 75a and an upper large-flow-rate opening 75b. The level sensor 76 has a float 76a floating near a liquid surface within the horizontal pipeline, and detects a liquid level L within the horizontal pipeline. The lubricant flow sensor 70 further has a hollow protecting tube 78.SELECTED DRAWING: Figure 2
