ProConsole Torque Calibration

Calibration using a Known Weight

  1. Install the calibration arm onto the dynamometer.
  2. Press the STOP key on the console operator’s panel.
  3. Press The F key for the Autozero.
  4. Press the B key for All Channels.
  5. Place a known weight of between 100 and 300 pounds on the calibration arm. The exact weight must be certified to the nearest pound.
  6. Calculate the torque value of the weight by multiplying the weight value times the length of the calibration arm (in feet).

Fundamental Concepts to Achieving Superior Repeatability

Fundamental Concepts to Achieving Superior Repeatability

The following concepts were originally presented by Jim McKenzie of Hendrick Engines Dynamometer Labs during the 1998 AETC conference. These are intended as guidelines for using an engine dyno and obtaining maximum repeatability in the results. Following these guidelines can result in +/- .1% repeatability. SuperFlow engineers added additional guidelines to get the most from your SuperFlow product.

Fuel System Troubleshooting

The purpose of this document is to help you understand how the dynamometer fuel system works so you can troubleshoot the fuel system and perform a basic calibration routine to increase your fuel measurement system’s accuracy. This document is written with the SF-901 dynamometer system in mind, but the basic theory applies to all SuperFlow engine dynamometer systems. The photos were taken from an SF-901 system.

3200P-0750 Pump Seal Replacement

Jan 21, 2009


3200P-0750 Pump Seal Replacement

All water brake absorbers manufactured by SuperFlow Technologies Group use the 3200P-0750 pump seal. The purpose of this seal is to prevent water from moving between the rotor and stator area and the pump housing. Failure of this seal can lead to absorber controllability issues such as reduced loading capacity, surging, and erratic changes in load.

Clearing SF-901 NOVRAM

The corrupt NOVRAM message appearing at WinDyn startup can sometimes be resolved by sending your SF-901 Sensor Calibration file to the dyno using the WinDyn>>Calibrate>>SF-901 Sensor menu option. Open the sensor menu, then open an existing calibration file and reinstall it into the dyno using the Install, Save, and Exit function in the Sensor Calibration Menu dialog box.

XConsole Torque Calibration

A common call to the SuperFlow Technical Support Department involves questions about torque readings and power numbers obtained from the dyno. Most often, the complaint involves torque or power readings that are too low. In many cases, proper attention to torque calibration will solve the problem. Accurate calibration of the torque system can only be accomplished by carefully following this procedure.

SF-833/871 Absorber Pump Seal Test
  1. Place the dynamometer's load controller to minimum load. This ensures that the servo valve is wide open.
  2. Fully loosen the lock nut on capacity valve.
  3. Turn the capacity valve fully counterclockwise (open).
  4. Remove the capacity valve from the back of the absorber pump housing.
