Lincoln Ventmeter, as a simulation device of a centralized lubrication system, consists of 25 feet coil tube with valve 1 at the pressure gage end and valve 2 at the end where a level grease gun is connected. Build up pressure with the grease gun attached when valve 1 closed. Open instantly valve 2 when
pressure gage reading stabilizes at 1800 psi. Read the pressure gage after venting for 30 seconds. Repeat test three times and take an average reading to determine supply line pipe size and maximum length of supply line.
Test under Different Temperature ñ The test could be done under any
temperature as application required. The standard test recommend three
temperature: 0ƒF, 30ƒF and 75ƒF. When testing under temperature other than
the ambient, the ventmeter filled with grease should be put in temperature
chamber for at least 4 hours. The same test steps should be used for different temperature conditions.
