Thermal Mass Flow Controllers, and Thermal Mass Flow Meters, are just part of the Mass Flow Instrumentation manufactured by Teledyne Hastings Instruments. Hastings Instruments also manufactures Vacuum Instruments. Hastings, Thermal Mass Flow, Instruments and Vacuum Instruments are designed for the precise measurement and control of vacuum and gas flows.

The heart of the system is a replaceable sensor which virtually eliminates long downtimes due to clogging, the most common cause of failure in the industry. The modular design also offers adjustable range capabilities, in-line filtration, and replaceable electronics to allow users maximum flexibility in adjusting their system for changing requirements. Current designs can accommodate flow rates from 10 SCCM to 15,000 SLPM, fast responding or zero overshoot electronics.

The current Models HFM Mass Flow meter and HFC Thermal Mass Flow Controllers represent the culmination of more than 55 year’s experience in manufacturing quality thermal mass flow instruments. The basic design incorporates removable replaceable components to provide users a low cost of ownership, maximum flexibility, and reduced downtime.

Recently, new all metal-seal 300 Series Metaline(r) meters and thermal mass flow controllers have been introduced both in analog and digital versions. They are designed to accurately measure mass flow without corrections or compensations for gas pressure and temperature. These are highly accurate instruments which approach a 0.5% of reading accuracy (digital instruments) level.

These Hastings thermal mass flow instruments do not require periodic maintenance under normal operating conditions with clean gases. This product line features settling times less than 0.55 seconds.

The latest product line developed by Teledyne Hastings Instruments is the digital version of the high capacity flow instruments. These new digital instruments allow measurement and/or control up to 10,000 slm. The new line complements the existing lower flow Digital Metaline (5 sccm to 30 slm).
