PRIMARY STANDARD LIQUID CALIBRATION SYSTEMS - MICROTRAK/OMNITRAK

Flow Technology’s Microtrak and Omnitrak positive displacement computer–assisted liquid flowmeter calibration systems provide performance, reliability and economical benefits of ownership.

Exceptional accuracy and stability are achieved from a precisely honed, chrome–plated stainless steel cylinder used to displace the fluid used for calibration.

QUICK SPECS

  • Ballistic Primary Standard Calibrator for Liquids
  • Flow range of 0.001 to 400 GPM (0.004 to 1500 LPM)
  • ± 0.05% uncertainty of volumetric flow rate measurement (95% C.L.) typical
  • Flowmeter pulse, magnetic pickoff, RF pickoff and manual inputs std. (Analog inputs available)

KEY BENEFITS

Performs complete liquid flowmeter calibration in minutes
Small calibration fluid volume minimizes fluid inventory
Calibrates all principal meter types including: coriolis, electromagnetic, positive displacement, turbine, orifice, variabel area, venturi, vortex
Field calibration using water draw validation

Flow Technology's Autobell primary standard gas calibration system accurately measures displaced volume of gas at a constant pressure.

PRIMARY STANDARD GAS CALIBRATION SYSTEM - AUTOBELL®

The Autobell®, a primary standard gas calibration system, is used to accurately measure a displaced volume of gas at a constant pressure. Interface electronics are provided to measure displaced volume and the time over which the volume is displaced so that a precise flow rate can be determined.

To calibrate a gas flow meter using the Autobell®, the flow meter must be installed upstream of the bell so that all gas flowing through it is captured by the calibrator.

QUICK SPECS

  • Primary standard gas calibration system
  • Flow range of 0.1 to 125 ACFM (2.83 to 3540 ALPM)
  • +/- 0.2% uncertainty of volumetric flow rate measurement (95% C.L.) typical
  • Interface using menu driven CalWare software

KEY BENEFITS

Directly traceable to NIST
Stainless Steel Construction provides durability
Calibrates all principal meter types including: turbine, variable area, thermal
Automatic data acquisition through PC and interface
Automatic level compensation for liquid seal volume
