Hastings Flow Meter Catalog: High-Precision Electronic Gas Volumetric Transmitters for Clean Labs
Quick Answer
For clean lab gas flow measurement, a Hastings flow meter catalog lists thermal volumetric transmitters that read in sccm or slm. Silver Instruments supplies compatible gas flow meters with 4-20 mA HART output and RS485 Modbus. Send your gas type, flow range, pressure, temperature, and pipe size for a quote.
Clean Lab Gas Flow Needs Specific Hardware
Clean labs handle nitrogen, argon, helium, oxygen, carbon dioxide, and sometimes forming gas. Flow rates often sit between 5 sccm and 50 slm. Process engineers need repeatability more than anything. A drift of 1 sccm on a purge line can ruin a batch or shut down a tool.
Most clean lab gas panels use small tube lines from 1/8 inch to 1/2 inch. Wetted parts should be 316L stainless steel or Hastelloy C. The meter body must not leak. Clean labs do not tolerate elastomers that outgas. Standard VCR and Swagelok tube connections are common. For a DN15 clean gas main, the SGMF with 1/2 inch connections usually works well.
What the Hastings Flow Meter Catalog Tells You
The Hastings flow meter catalog focuses on electronic gas volumetric transmitters for vacuum coating, leak testing, semiconductor tools, and laboratory research. Typical output is 0-5 VDC, 4-20 mA, or RS232. Many units have small mass flow sensor tubes and low pressure drop.
We see many customers with an old Hastings HFM-200 or HFC-202 unit that is no longer supported. They want a replacement without new plumbing. Silver Instruments can match face seal, VCR, NPT, or Swagelok connections on request. In practice, most engineers skip the full catalog review and ask for a dimensional crossover first.
Silver Instruments Gas Volumetric Transmitter Options
The Silver Instruments SGMF series is a thermal mass flow meter for clean gas lines. The SGMF covers DN3 to DN25. Standard flow ranges run from 0-5 sccm to 0-300 slm. Reference conditions can be set to 20 °C and 101.325 kPa or 0 °C and 101.325 kPa depending on plant data logging.
Output options include 4-20 mA HART, RS485 Modbus RTU, and pulse. The local display shows flow in sccm, slm, Nm3/h, or kg/h. Power is 24 V DC. Accuracy is ±1.0 percent full scale for standard models. Higher accuracy ±1.5 percent reading plus 0.5 percent full scale is available for low flow ranges.
Wetted parts are 316L as standard. Hastelloy C is available for corrosive gas. Process temperature can be from 0 °C to 50 °C for standard models. Maximum pressure is 10 bar for small tube flow meters. For clean lab gas panels, the flow meter has less than 0.02 bar pressure drop at full scale.
Model Selection with Real Numbers
For a nitrogen purge cabinet at 0-100 sccm, pick the SGMF-100 with 1/8 inch VCR male and 4-20 mA HART. This setup fits most semiconductor clean ro
For a pharmaceutical clean room blanket at 0-50 slm, choose the SGMF-50L with 1/2 inch Swagelok connections, Modbus RTU, and local display. A buyer in Australia used this model to replace an older volumetric transmitter on a nitrogen distribution line.
For oxygen sparging in a bioreactor at 0-10 slm, choose 316L wetted parts and specify oxygen cleaned service. Fluid temperature is usually 20 °C to 30 °C. Line pressure rarely exceeds 2 bar in this application. If you are not sure about the fitting, send a photo of the old meter.
Installation Notes for Clean Labs
Mount the meter with 10 DN straight upstream and 5 DN downstream when possible. Avoid condensing moisture in the sensor tube. Compressed air lines from house supply often carry oil mist and water. A 0.3 micron coalescing filter upstream helps a lot.
If the clean lab is in an ATEX Zone 1 area, select the Ex d version. We ship to Southeast Asia, Middle East, Latin America, and Australia. Last year a customer in Vietnam asked us for an Ex d gas transmitter because the lab was inside a solvent handling room. The standard aluminum housing did not pass the safety review.
This gas flow meter is not for liquid. If your clean lab also measures water, buffer, or another liquid with viscosity in cP or conductivity in µS/cm, use an electromagnetic flow meter or Coriolis mass flow meter from our range. An external PT100 can be connected for gas temperature compensation on some SGMF models.

FAQ
1. Can Silver Instruments replace a Hastings gas volumetric transmitter without changing piping?
Yes. Many HFM and HFC models with 1/8 to 1/2 inch VCR or Swagelok can be matched. Send the old connection size and a photo.
2. What output signal is best for clean lab gas flow?
4-20 mA HART is the standard for process control. Modbus RTU works better for multi-drop data logging in a rack.
3. Do you calibrate for nitrogen, oxygen, carbon dioxide, and helium?
We factory calibrate on nitrogen. Conversion factors for oxygen, carbon dioxide, helium, and argon are available. We can also provide actual gas calibration for oxygen and helium.
4. What is the typical lead time for a clean lab gas flow meter?
Standard models ship in 10 to 15 days. Oxygen cleaned models add 3 days. Express shipping is available for one or two pieces.
5. Can the flow meter be cleaned for oxygen service?
Yes. We provide oxygen cleaning and degreasing. The process follows common industrial cleaning standards for oxygen lines.
