Features in the Series J category include stainless steel reading scales of capacity in compliance with A.P.I. Code 1101 and N.I.S.T. HB-105-3. Measures in excess of 10 US gallons are commonly referred to as provers.
Equipped with an overflow trough and drain-cock to prevent voiding your test, Series J Provers are made with a well-pitched bottom with a center draught connected to a drain brought forward to a shut-off value and are equipped with three heavy duty, adjustable pipe legs. In each unit, the neck is equipped with a center draught connected to a drain-cock for setting the measure at zero when the neck test measure is to be drained into the device being tested. The inside is constructed so that the prover is free of bubbles when filled to assure that no liquid is entrapped when the unit is drained.
Gauge fixtures are entirely on the outside of the neck of the unit to keep the neck free from any construction or obstruction, and to assure the accuracy of the area of the neck at each graduation throughout the length of the reading scale.
All parts of the gauge fixture can be removed and reassembled at will without the slightest danger of damage or change of accuracy as long as the lock pin is not removed. Also, adjustments can be made without emptying the measure or taking it apart, by first removing the seal and lock pin and then turning the adjusting rods to the change desired.
Measures are equipped with two leveling gauges and a standard "butterfly" value. Other type valves are available. Thermometers and casters are also available at extra cost.
Also available are "Special J" Measurers that are normally truck mounted and incorporate the same basic features as used in the Series J models.
