Badger Meter Portable Hydraulic Testers - Manual (Page 9)

TEST PROCEDURES
ALL TESTERS ARE SHIPPED WITH THE LOADING VALVE IN THE CLOSED POSITION. THE LOADING VALVE MUST BE
OPENED FULLY BEFORE INITIATING FLOW AND TESTING THE HYDRAULIC CIRCUIT. TURN THE LOADING VALVE HANDLE
COUNTERCLOCKWISE TO THE FULLY OPEN POSITION. FAILURE TO OPEN THE LOADING VALVE FULLY CAN RESULT IN
INJURY TO PERSONNEL AND/OR DAMAGE TO THE EQUIPMENT.
THE INFORMATION IN THIS MANUAL IS FOR GENERAL APPLICATION ONLY. ANY INFORMATION FURNISHED BY THE
MANUFACTURER OF THE MACHINE’S HYDRAULIC COMPONENTS SHOULD BE FOLLOWED. SPECIFIC SYSTEMS MAY
REQUIRE SPECIFIC TEST PROCEDURES.
General Information
The PFM6 and PFM6BD testers are designed to measure flow, pressure and temperature . The PFM8 testers are also designed
to measure power .
The power measurements are derived from the product of flow and pressure . When using a PFM6 or PFM6BD, power can be
calculated using the formulas in “Hydraulic Formulas and Viscosity Information” on page 17.
Standard Test Conditions
1 . Install the PFM tester as described in one of the following test procedures:
a . “Pump Test” on page 10
b . “Tee Test” on page 11
c . “Control Valve, Cylinder and Hydraulic Motor Test” on page 12
d . “Relief Valve in Separate Housing” on page 12
e . “Relief Valves” on page 13
2 . Open the loading valve fully by turning the handle counterclockwise .
3 . Start the pump and adjust it to rated speed .
4 . To raise the system temperature, close the tester loading valve to develop a pressure somewhat below the relief valve
pressure . Maintain pressure until the desired temperature is reached .
5 . Open the tester’s loading valve fully and proceed with the required test procedure .
6 . The tester will display flow, pressure, temperature and power readings .
