Thermal Mass Flow Meter Price: Commercial Procurement and Cost Benchmarks
Quick Answer
A basic inline thermal mass flow meter for air or nitrogen from Silver Automation Instruments typically starts at around USD 850 for DN15. Insertion models for large pipes, ducts, or stacks cost from USD 1200 to USD 3800. A realistic procurement benchmark for most gas metering jobs is USD 1200 to USD 5200 before optional ATEX, high temperature, or digital protocol upgrades.
Price Structure and Main Cost Drivers
Here is the thing. The price of a thermal mass flow meter is not fixed by one part. It follows the cost of sensor elements, transmitter electronics, body material, insertion hardware, display type, and certification. A meter with local display, 4-20 mA output, and standard air calibration costs less than a blind unit with HART and ATEX Zone 1.
Silver Automation Instruments sells both inline and insertion thermal mass flow meters. Inline models suit DN15 to DN100 pipes. Insertion models suit DN80 to DN2000 pipes and rectangular ducts. Probe length, flange material, and mounting method also change price. A 316L stainless steel body with PT100 RTD elements is common for standard gas service.
Most engineers skip this part but it matters. Calibration gas and reference conditions drive part of the commercial cost. Standard calibration for air or nitrogen is often included. Calibration for biogas, hydrogen, flue gas, or natural gas can add USD 200 to USD 600 depending on the gas mix and flow range.
Price Ranges for Standard Models
Inline thermal mass flow meters for air and nitrogen from Silver Automation Instruments start at about USD 850 for DN15. Typical DN25 to DN50 inline meters cost USD 1200 to USD 2500. Inline DN65 to DN100 versions run from USD 2800 to USD 5200 because the body and flow conditioner are larger.
Insertion thermal mass flow meters are the cost effective choice for pipes above DN100. A standard insertion probe with local display and 4-20 mA output usually costs USD 1200 to USD 3800. The final price depends on probe length, compression fitting or flange, and whether the buyer needs hot tap installation hardware.
Optional features affect totals. HART protocol is usually a small add on or included depending on the model. RS485 Modbus RTU output adds USD 80 to USD 180. ATEX or IECEx certification adds 15 to 30 percent depending on zone and gas group. High temperature probes for stack gas up to 300 °C cost more than standard probes rated to 200 °C.
Application Based Benchmarks
We have seen this on customer sites many times. Compressed air monitoring in food and beverage plants usually uses inline DN25 to DN80 meters. Budget USD 1400 to USD 3200 per line with standard air calibration.
A paint manufacturer in Southeast Asia recently ordered 12 insertion thermal mass flow meters for compressed air lines from DN80 to DN200. The unit price landed at USD 1680 because standard air calibration and RS485 were include
For oil and gas fuel gas measurement, Middle East and Latin America buyers often require HART, stainless steel tags, and calibration reports. These meters usually land from USD 2800 to USD 6500 depending on pressure rating and hazardous area certification. For wastewater aeration air and digester gas, buyers in Oceania and Africa typically choose insertion meters with local display and one analog output.
How to Get a Firm Quote from Silver Automation Instruments
Do not send only the keyword thermal mass flow meter price. Send gas type, flow range in normal cubic meters per hour or kg/h, pipe size in DN, process pressure in bar, process temperature in °C, and required output signal. Add any certification zone if the site is hazardous.
Example. A DN25 compressed air line at 7 bar and 25 °C with a range of 0 to 200 Nm3/h can use a standard inline meter with local display and 4-20 mA HART. A DN200 biogas line at 1 bar and 40 °C can use an insertion meter with ATEX Zone 2 and RS485 Modbus RTU.
You can call or message Silver Automation Instruments at Tel: +86-25-68650347, Whatsapp: +86-25-52155837, or WeChat: +86 15365082610. Send us your pressure (bar), temperature (°C), pipe size (DN), and flow range. Our application engineers will return a fixed quotation with lead time and shipping terms.
For liquid mass flow, thermal mass flow is not the right fit. Use a Coriolis mass flow meter for kg/h liquid flow or an electromagnetic flow meter for conductive water based fluids above 5 µS/cm. Silver Automation Instruments supplies those lines as well from flow-meter.com.au.
FAQ
What does a thermal mass flow meter price include?
It includes the meter body or insertion probe, transmitter electronics, local display where specified, standard air or nitrogen calibration, 4-20 mA output, and a test report. Optional HART, RS485, ATEX, high temperature probes, and mixed gas calibration add cost.
Is a thermal mass flow meter suitable for liquid?
No. Thermal mass flow meters measure gas mass flow by thermal dispersion. Use a Coriolis meter for accurate liquid mass flow or an electromagnetic meter for conductive water and wastewater.
How do I choose between inline and insertion?
For DN15 to DN100 inline is easier to install and gives stable accuracy. For DN100 and larger insertion reduces cost and allows hot tap installation without process shutdown.
What information is needed for a quote?
Provide gas type, flow range, pipe size, pressure, temperature, output signal, power supply, and hazardous area zone. Send this to Tel, Whatsapp, or WeChat.
What is the typical lead time?
Standard models ship in 5 to 10 working days. ATEX certified units and custom gas calibrations often add 7 to 15 working days.
