SOFTWARE PACKAGE FOR COMPUTATION OF PRESSURE MEASUREMENT AND ESTIMATIONOF MEASUREMENT UNCERTAINTY USING DEAD WEIGHT TESTER

INTRODUCTION

This software, available in executable mode for commercial use, is a complete package developed in MSDOS QBASIC environment for the calibration of both hydraulic and pneumatic pressure measuring instruments using simple / reentrant type dead weight testers as pressure standards. This package can be used for the; computation of pressure generated / measured by a simple / reentrant type dead weight testers, after applying all possible correction factors as per well established theory of pressure balances; calibration of pressure dial gauges, simple / reentrant type dead weight testers and pressure transducers / Transmitters; characterization of dead weight testers for the computation of metrological characteristics i.e. zero pressure effective area, effective area as a function of applied pressure and distortion coefficient; conversion of different user friendly pressure units viz. Pa, kPa, MPa, bar, kg/cm2, mbar, torr, mmHg, mmWC, inWC, and psi; estimation of measurement uncertainties associated with pressure and effective area measurements as per ISO and NABL Guidelines.

TARGET GROUP / USERS

  • The NABL approved accredited pressure calibration laboratories.
  • The industries directly or indirectly using pressure measuring instruments or are involved in pressure metrology.
  • Any R & D Institute / laboratory, College and University involved in pressure metrology.
