Hastings HFM 300 Analogue Series
Fast Response Mass Flow Meters and Mass Flow Controllers 300 Series

Mass flow techniques provide more RELIABLE, REPEATABLE and ACCURATE gas flow rate measurements compared to volumetric methods such as rotometers and turbine meters. Mass flow measurements use the density of the gas to translate mass flow units (kg or lbs) to units of familiar volumetric terms (litres/min). However the measurements are still mass units (we call those units STANDARD liter/min (slm)) and they do not change with temperature and pressure changes. We do this by referencing just one, specific temperature and one specific pressure (STP).

300 Series mass flow instruments have flow ranges from 0-5 sccm to 0-3,000 slm; use all metal seals, provide analog outputs, and are constructed of stainless steel. The mass flow controllers have normally closed valves. Corrosive gases, with the exception of the halogens, pressures up to 1000 psig (optional) are easily measured.

General Purpose Mass Flow Meters and Mass Flow Controllers 200 Series

Mass flow techniques provide more RELIABLE, REPEATABLE and ACCURATE gas flow rate measurements compared to volumetric methods such as rotometers and turbine meters. Mass flow measurements use the density of the gas to translate mass flow units (kg or lbs) to units of familiar volumetric terms(litres/min). However the measurements are still mass units and we call those units STANDARD litre/min (SLM) and they do not change with temperature and pressure changes. We do this by referencing just one, specific temperature and one specific pressure (STP). For a more detailed explanation, see Mass Flow vs. Volumetric Flow.

200 Series instruments have flow ranges from 0-10 sccm to 0-500 slm (Large flows to 15,000 slm with a Laminar flow element); use elastometric seals, provide analogue outputs, and are constructed of stainless steel. The controllers have normally closed valves. Corrosive gases, with the exception of the halogens, pressures up to 1000 psig (optional) are easily measured.
