FLUICAL^®
Bench-Top Calibration System

General

Bronkhorst High-Tech have developed a bench-top calibration system to meet the increasing demands of users of measurement and control equipment within the ISO-9000 quality control system. The FLUICAL^® Bench-Top Calibrator offers great accuracy, traceable to national standards. As an option, our ISO 17025 accredited Bronkhorst Calibration Centre can offer calibration services for FLUICAL flow calibration systems.

Description

With Bronkhorst's FLUICAL^® Bench-Top Calibration System (Mass) Flow Meters and Controllers for gases can be accurately calibrated. It is an automatic system that consists of one or more calibration devices and an interface / readout / control unit. For flows to a maximum of 10 l/min piston provers can be used, whilst higher flow rates can be calibrated using high-accuracy rotor meters (maximum 100 m³/h).

The piston prover is a volumetric calibration device consisting of a precision bore borosilicate glass tube and a mercury sealed piston. When a gas flow enters into the vertical mounted glass tube the piston will move upwards. A number of sensors have been mounted along the wall of the tube to detect the presence of the piston. The volume between these sensors has been calibrated and is therefore a fixed known volume. Together with the travel time, pressure and temperature in the glass tube, the flow at reference conditions can be calculated.

The FLUICAL^® piston provers and rotor meters can be controlled by means of the Bronkhorst High-Tech series E-7000 digital readout and control system. With an optional RS232 - interface the FLUICAL^® system can be connected to and controlled be means of a personal computer. Normally the FLUICAL^® calibration devices are provided with Bronkhorst High-Tech calibration certificates. If required the calibration devices can be certified by VSL, the independent measurement authority in the Netherlands.
