Flow Meters Selected for Experimentation

Custom flow meter manufacturer and distributor Litre Meter has supplied Sierra Smart-Trak and Micro-Trak volume flow meters to state of the art research facility,Diamond Light Source for use in ionisation and X-ray

experimentation.

Scientists at the facility have selected Micro-Trak™ and Smart-Trak digital mass flow meters to control the flow of gases used for various scientific applications.

The Micro-Trak™ 101 series incorporates new, state-of-the-art sensor technology and a precision-engineered direct acting valve design to measure ultra-low gas flow accurately and reliably. The instrument has been designed to operate at flow ranges under 4 standard cubic centimetres per minute (sccm) with a minimum controllable mass flow rate of 0.1 sccm. It is highly stable and delivers a measurement accuracy of +/- 1.0% full scale and +/- 0.2% repeatability.

Micro-Trak™ has a stainless steel flow path and elastomer seals that eliminate the possibility of leaks. It is suitable for use in most applications involving clean gases, including those that involve corrosive and toxic gases. Smart-Trak and Micro-Trak™ incorporate Sierra’s state-of-the-art Dial-A-Gas®. Its internal microprocessor is pre-programmed with ten gases that are commonly used in biotech, pharmaceutical, analytical and research applications – others gases can be substituted to customise the flowmeter for applications. This technology allows the instrument to be used for multiple applications, creating great flexibility as well as helping to reduce spares inventory.
