ABB Mass Flow Meter: Thermal and Coriolis Gas Process Telemetry Systems
Quick Answer: ABB thermal mass flow meters measure gas mass flow directly and work well for air, biogas, and natural gas lines. Coriolis mass flow meters add density and temperature data for gas process telemetry systems that need tighter mass balance. Silver Automation Instruments supplies thermal and Coriolis mass flow meters with 4-20 mA HART, pulse, and Modbus outputs for gas process telemetry across Southeast Asia, Oceania, the Middle East, Africa, and Latin America.
Engineers often search for ABB mass flow meter options when a gas process telemetry system needs a stable flow signal. They want a meter that connects to PLC, SCADA, or flow computer without extra signal converters. The common choices are thermal mass flow meters and Coriolis mass flow meters. The right choice depends on gas wetness, line size, accuracy needs, and whether the control room needs density.
Thermal Mass Flow Meter for Gas Telemetry
Thermal mass flow meters use a heated sensor and PT100 temperature elements. The meter measures heat loss caused by gas flow. It calculates mass flow in kg/h or Nm3/h directly. There is no need for separate pressure or temperature compensation on many clean gas lines. This makes thermal meters easy to integrate into gas process telemetry systems.
Typical line sizes run from DN15 to DN100. Accuracy is usually 1.0 to 1.5 percent of reading. Common outputs are 4-20 mA HART, pulse, and RS485 Modbus. Hazardous area versions are available for ATEX Zone 1 or Zone 2. We have supplied thermal mass flow meters for compressed air, nitrogen blanketing, biogas, and natural gas lines in Vietnam, Indonesia, and the Philippines.
Coriolis Mass Flow Meter for Gas Process Data
Coriolis mass flow meters measure mass flow, density, and temperature from one sensor. They are often selected for gas process telemetry when density is important or when the gas composition changes. Coriolis meters are accurate to 0.1 or 0.2 percent of rate in many gas applications. Common gas line sizes are DN15 to DN80. These meters handle higher pressures and provide strong signal repeatability.
Here is the thing. Coriolis meters cost more than thermal meters. But they solve problems thermal meters cannot solve. A gas blending system in Singapore needed mass flow and density data for a reactor feed line. We supplied a Coriolis mass flow meter with 4-20 mA HART and pulse output. The customer connected the signals to a flow computer and removed a separate density meter. That cut installation cost and wiring time.
Telemetry Output and Signal Integration
Most gas process telemetry systems use 4-20 mA HART as the primary analog signal. Some sites still use pulse output for totalized flow. Many new installations ask for Modbus RTU or Modbus TCP. Silver Automation Instruments can supply 4-20 mA HART, pulse, or RS485 Modbus. We pre configure the range, units, slave ID, and baud rate before shipment. That saves commissioning time.
In practice, most engineers skip the full data sheet. They send a photo of the existing nameplate or wiring diagram. We match the flow range, process connection, and electrical output. For ABB mass flow meter replacements, we also check whether the cable entry is M20 or 1/2 inch NPT. This small detail reduces site wiring changes.
Where Each Meter Type Fits in Gas Processes
3>
Thermal mass flow meters fit well in aeration air, biogas collection, flare gas monitoring, and compressed air distribution. They are easy to install but should not be used with wet gas or heavy condensation. Coriolis meters fit better in gas feed blending, reactor mass balance, and custody transfer. They need more straight pipe support and cost more upfront.
We have seen this on customer sites many times. A wastewater plant in Vietnam used thermal mass flow meters on blower air lines. The maintenance team checked flow from the SCADA without walking to the blower room. A chemical plant in Chile used a Coriolis meter on a gas sparging line because they needed density for mass balance calculations. Two different gas processes. Two different meters.
ABB Mass Flow Meter Comparison and Replacement Path
ABB supplies thermal mass flow meters and Coriolis mass flow meters for gas process telemetry. Their ABB Sensyflow series is common for thermal gas flow. The ABB CoriolisMaster series is used where density and mass flow are needed. Silver Automation Instruments is a flow meter manufacturer and supplier based in China. We are not an ABB distributor. But we can supply compatible or alternative mass flow meters for many ABB gas flow applications.
If you send us the existing tag number or model code, we can cross check the flow range and sensor type. We need the gas name, minimum and maximum flow in kg/h or Nm3/h, operating pressure in bar, operating temperature in Celsius, pipe size in DN, and output signal. For hazardous areas, tell us the zone and gas group. Send that information to WhatsApp or WeChat for a fast model and price.
FAQs
Can Silver Instruments replace an ABB thermal mass flow meter for gas?
Yes. We supply thermal mass flow meters for gas with DN15 to DN100 line sizes, 4-20 mA HART output, and ATEX or non hazardous options. Send the existing model code and flow range.
What is the lead time for a Coriolis mass flow meter for gas process telemetry?
Typical lead time is 2 to 4 weeks for standard DN15 to DN80 models. Custom gas calibration may add 1 to 2 weeks. We ship by air or sea from China to Southeast Asia, Oceania, the Middle East, Africa, and Latin America.
Do your mass flow meters support Modbus telemetry?
Yes. Many models support RS485 Modbus RTU. Some support Modbus TCP through an optional converter. We normally set the slave ID and baud rate before shipment.
What information is needed for a gas flow meter quote?
Send gas type, minimum and maximum flow in kg/h or Nm3/h, operating pressure in bar, operating temperature in Celsius, pipe size in DN, and output signal. For hazardous areas, tell us the zone and gas group.
Can you calibrate a mass flow meter for mixed gas?
We can calibrate for air or nitrogen in our workshop. For mixed gas, we need the composition and may apply a correction factor. Some applications require factory calibration with the actual gas. Contact us with the gas mix details.
