Medium capacity flowmeters and controllers from Teledyne Hastings Instruments are available from Durham Instruments.

Medium capacity flowmeters and controllers from Teledyne Hastings Instruments (THI) are the result of a culmination of more than 60 years of experience in designing and manufacturing reliable, high-quality mass flow instruments. The HFM Mass Flowmeter and HFC Mass Flow Controller, referred to as the HFM/HFC 200 Series of flow instruments, have many features that make them a top choice for use in a wide range of applications, from leak testing and medical research, to gas blending, pollution monitoring and more. 

Best-in-class features

The HFM/HFC 200 Series is based on a modular design. Both the HFM-201 and HFC-203 models have an insulated thermal transfer sensor designed to provide enhanced zero stability and to be easily replaced in the field. This design is meant to eliminate long down time due to clogging. 

In addition, the HFM/HFC features an integral filter and an easily replaceable closed-loop electronics card, while the HFC also features a two-stage, pilot-operated control valve. 

Optional features include fittings, o-ring seals, enhanced response time, enhanced EMF stability, high pressure rating (1,000 psig) and 4-20 mA converters.

Applications and accessories

The two models in the HFM/HFC 200 Series can be used in many applications. Common uses include semiconductor processes, medical research, gas blending, leak testing, pollution monitoring, vapour deposition and more. 

To enhance the units' capabilities, a variety of accessories are available. For example, power supplies with integral flow totalizers and alarm set points are available, as well as interconnecting cables.
