Chell provides customers with a comprehensive calibration service covering all measurement instruments supplied by the company.
Chell Instruments offer a wide range of high quality and reliable mass flow meters, controllers and systems suitable for use in a wide range of applications and industries.
With over 40 years of experience in flow measurement and control, we are extremely well placed to assist in specifying and supplying instumentation for your application, from single instruments to bespoke automated systems. Chell's impressive calibration and repair facilities also allow us to offer comprehensive after sales support.
Chell Instruments are the UK distributor for the 'SAES Pure Gas' range of gas purification equipment. These offer incredible purification performance over a huge range of gases and flow rates through the use of absorber, adsorber, catalyst, heated getter and palladium membrane purification technologies.
We also supply a range of gas handling solutions, from full, bespoke gas panels to high performance needle valves and regulators.
Chell offer a wide range of equipment for the measurement and control of gas pressure. This could be a very high-end primary pressure standard, benchtop calibrator, portable calibrator or simply a single transducer. We can also provide bespoke, automated pressure measurement systems tailored to your exact process requirements.
Chell's impressive calibration and repair facilities also allow us to offer comprehensive after sales support.
Chell supply a range of temperature scanners to complement the pressure scanners
Chell Instruments offer a wide range of high quality and reliable vacuum measurement instrumentation for use in a huge variety of applications and industries.
With over 30 years of experience in vacuum measurement and control, we are extremely well placed to assist in specifying and supplying instrumentation for your application, from single instruments to bespoke automated systems.
Chell's impressive calibration and repair facilities also allow us to offer comprehensive after sales support.
The Chell VTS units are designed specifically to act as high accuracy mass and volumetric flow transfer standards, enabling easy and convenient verification of production gas meter calibration systems against your site flow reference.
High accuracy instrumentation and a custom low pressure drop manifold are built into a standard gas meter body, allowing installation onto your gas meter calibration system in place of a standard production meter.
Great care has been taken in the design of both the hardware and software to ensure the VTS enables a meaningful and reliable verification of both mass and volumetric flow rate.
•Allows easy verification of gas meter calibration systems
•High accuracy and excellent repeatability
•Compatible with most gas meter body variants
•Multiple flow ranges from 10 to 12000 l/hr
•Built in pressure and temperature instrumentation
•Linearising capability
•High resolution LCD display and cap-touch interface
•Ethernet communications with optional Bluetooth
•Supplied with calibration/logging software
Principal
The VTS is calibrated and linearised against your site flow reference.
The VTS is then installed onto the gas meter calibration system, such as one of the Chell GMCS range, and the standard meter calibration sequence performed.
The data obtained is then verified as being within the combined uncertainty of both the production calibration system and site reference.
Check can be performed as often as required as part of regular calibration checks, spot verification or troubleshooting.
Chell design and manufacture a full suite of gas meter calibration systems, site flow standards and verification instrumentation, as well as technical support services. Please contact our applications engineers to discuss your requirements.
