Typical accuracy curves for basic meter build (10:1 turndown)
Calibration adjustment is provided to minimize the meter error at any selected flowrate. Adjustment is stepless; no gear changing is necessary; and the calibration screw is easily accessible after breaking a seal and removing a sealing screw.
All meters are tested to 300 psi (21 bar).
All Avery-Hardoll meters are tested before despatch at a range of flowrates and test certificates can be supplied if requested.
The fluid used for testing is odorless kerosene.
Specific gravity at 60/60ºF, 15/15ºC = 0.8 Viscosity at 60ºF, 15ºC = 2.4 centistokes.
Suggested correction to be made to the calibrating mechanism when used with products with different viscosities as follows:
|Gasoline||+ 0.1%||+||means increase counter readings|
|Kerosene||0.0%||–||means decrease counter readings.|
