Industrial diaphram sonic nozzle calibrating system

Home > G/M Certification and Calibration > Industrial diaphram sonic nozzle calibrating system

Principle

 It is a system which uses the principle to measure the volume after measuring the flow rate of mass by the congested temperature and pressure of the upper part of sonic nozzle.

Composition

  • Nozzle bank: 1EA
  • Nozzle: 6 unidades (caliber: 0.2mm~3.2mm)
  • Pressure gaug (8EA): Absolute pressure gauge (3EA), differential pressure gauge (5EA)
  • Industrial resistance thermometer: 7EA (nozzle and flowmeter)

Features

  • Scope of verification : 0.06㎥/h ~ 40㎥/h
  • It is possible to verify 5 meters at the same time
  • System uncertainty : 0.25%

Purpose

Certification of diaphram meter (G6~G25)
