This vacuum water lift gauge measures water lift (vacuum) at a sealed
opening. Place on the end of vacuum pipe and read the dial to determine
suction power. Measures from 0 to 160 inches of water lift.
When you are trying to determine the
water lift on any vacuum system it is important to understand what the
terminology "Water Lift" really means.
Water lift is a measurement of the
strength of any vacuum that is produced by the suction that the motor(s)
the system uses to produce that suction. Water lift suction gauges used
on vacuum systems and are calibrated in what is referred to as "Inches
of Water Lift". So to put this in a practical manner it is the
equivalent to taking a vertical tube, placing the bottom in a container
of water then attaching a vacuum hose to the top of the tube and
measuring how high above the water surface the water in the tube rises.
For those who are technically oriented
one cubic inch of water weighs 0.036 pounds. Therefore the negative
pressure in pounds per square inch can be determined by multiplying the
water lift that is displayed on your water lift gauge by 0.036. In
addition, if you are using suction that uses a millibars (mbar) rating
system you may multiply that number by 0.4 to convert it to inches of
water lift.
Measurements are 4 inches long and 2 1/2 inches wide ~ Item is brand new in box ~ A must for any vacuum store or used vacuum seller!
