Gas flow calibrators require low
maintenance
One type of a range of portable low-maintenance primary standard gas flow calibrators is claimed to offer the best accuracy of any commercially available standard: +/-0.15% of reading.
Sierra Instruments' portable low-maintenance primary standard gas flow calibrators are the Cal-Trak SL-500 and Cal-Trak SL-800 Sierra, one of world's most preferred gas flow meter manufacturers, presents the much anticipated successors to its well-known, but discontinued Cal-Bench line of primary standard piston provers of the1990's

Gas flow meter for natural gas flow measurement applications is designed to provide an economical and easy to install solution for natural gas measurement in heaters and boilers.
Mass flowmeter maker opens Chinese office
A major US manufacturer of mass flow meters and controllers used in the semiconductor, pharmaceutical and various general process control applications has opened a strategic office in China.
The Cal-Trak SL-500 offers an excellent accuracy of +/-0.4% of reading while the Cal-Trak SL-800 offers the best accuracy of any commercially available standard: +/-0.15% of reading.
Sierra customers use Cal-Trak in the manufacture, inspection, validation and recalibration of mass flow controllers, mass flow meters and numerous other varieties of gas flow measurement and control instrumentation.
Cal-Trak operates in the 5 sccm up to 50 slpm flow range.
The broad turndown ratio allows three interchangeable flow cells to cover the entire range.
Alternatively, the modular nature of the Cal-Trak allows the user to begin with one flow cell and then add other cells as resources allow--creating the need for only a minimal initial investment from the customer to get started.
Sierra's Cal-Trak line provides primary NIST traceability, is manufactured under strict ISO 17025 certification, and is CE approved.
The dimensionally-based primary accuracy of Cal-Trak is superior to pressure-based secondary methods and is backed by a rigorous uncertainty analysis.
Both Cal-Trak models offer data logging, digital communications, interval operation and many other productivity-enhancing features.
Fast enough to use as a flow meter, Cal-Trak is automatic and requires minimal training to get started.
It is well-suited for applications in the metrology, semiconductor, analytical, medical and pharmaceutical fields, among many others.
