Aalborg Instruments Flow Meter: Sourcing Analytical Laboratory Fluid Tools
Quick Answer: Silver Automation Instruments supplies thermal mass flow meters, Coriolis mass flow meters, and small-bore oval gear meters for analytical laboratory fluid control. If you need a replacement for an Aalborg Instruments flow meter or a compatible meter for a new analyzer build, send your fluid type, flow range, pressure, temperature, connection size, and output signal. We will return a specific model with price and lead time.
If you search for Aalborg Instruments flow meters, you likely run a laboratory or OEM analyzer system that requires repeatable gas or liquid flow control. Silver Automation Instruments sells direct to labs, pilot plants, and analyzer builders in Southeast Asia, Oceania, Latin America, Africa, and the Middle East. The product range covers thermal mass flow meters for gases, Coriolis mass flow meters for liquids and gases, electromagnetic flow meters for conductive liquids, and oval gear meters for dosing and batching.
Why lab buyers search for Aalborg Instruments flow meters
Aalborg is a known brand in analytical and laboratory flow instrumentation. Their thermal mass flow meters and rotameters appear in gas chromatography, bioreactors, glove boxes, and sample conditioning systems. When a lab manager or process engineer types that keyword, the real need is usually one of three things.
First, a replacement meter with the same footprint and signal output. Second, a lower cost equivalent for a new analytical skid. Third, a faster lead time because a research project cannot wait 8 to 10 weeks. Our production team in Nanjing stocks common thermal mass flow meter ranges from 0 to 10 sccm up to 0 to 1000 slpm.
What actually matters in analytical fluid tools
Most engineers skip this part, but the fluid path design decides whether the data stays repeatable. For gas analyzers, wetted parts should be 316L stainless steel with Viton or Kalrez seals. Our GF thermal mass flow meter series uses 316L wetted parts, NIST-traceable calibration for air and nitrogen, and optional multi-gas calibration factors for CO2, argon, helium, and methane. Accuracy is ±1 percent of full scale, with repeatability of ±0.2 percent full scale.
For liquid reagent dosing, a Coriolis meter gives direct mass flow and density. We recommend the SMF Coriolis series for flows from 0 to 2 kg/h up to 0 to 1000 kg/h. The meter has 4-20 mA HART, RS485 Modbus, and can measure density from 0 to 3000 kg/m3. That data helps a lab confirm the correct reagent concentration before the stream reaches an analyzer.
Replacement paths for common Aalborg gas flow meters
In practice, the fastest replacement starts with the tube size and flow range. Many Aalborg GFC mass flow controllers use 1/8 inch, 1/4 inch, or 3/8 inch compression fittings. Our GF series covers the same mechanical sizes. A customer in Singapore needed a 0 to 100 sccm air mass flow meter for a gas blending panel. They sent us the old analog voltage output requirement, which was 0 to 5 VDC. We set the meter to 0 to 5 VDC, 4-20 mA, and RS485 Modbus all at the same time. Lead time was 6 days with DHL.
For metal tube rotameters used in purge and carrier gas lines, a thermal mass flow meter often removes parallax error and gives a data log signal. If the application is purely visual, we also supply stainless steel and glass tube rotameters with needle valves. The valve type matters here. A 10-turn metering valve gives better low flow control than a 1-turn valve. Most lab technicians prefer the 10-turn version for columns and detectors.
Liquid analytical tools: small flow, fine control
Liquid flow in analytical labs is different. Flow rates can be 5 mL/min, 50 mL/min, or 500 mL/min. Pressure is often low. Tubing is 1/16 inch, 1/8 inch, or 3 mm OD. We have seen many customer sites where a standard industrial flow meter is too large and the pressure drop kills the sample flow. For these cases, we supply small-bore oval gear flow meters and micro Coriolis meters.

Signals and communication for analyzer integration
A flow meter in an analytical system is not a standalone device. It must talk to a PLC, a data logger, or a chromatography software package. We configure outputs on most meters as 4-20 mA active or passive, 0 to 5 VDC, 0 to 10 VDC, pulse, and RS485 Modbus RTU. Some labs still use Profibus DP. We can support that on thermal mass flow meters with an optional module.
Power supply is usually 24 VDC. The meter display can show sccm, slpm, kg/h, L/h, degrees Celsius, and total. We set the default screen based on the operator preference. A lab in Saudi Arabia wanted nitrogen flow in sccm and total in liters. That was configured before shipment.
How to size an analytical flow meter without guesswork
Send us these five values and we can size the meter in one working day.
Fluid type: gas or liquid, for example air, nitrogen, helium, water, methanol, or reagent mix.
Flow range: minimum and maximum in sccm, slpm, L/h, or kg/h.
Pressure: inlet and outlet in bar or psi.
Temperature: process and ambient in °C.
Connection: tube OD, pipe size DN, or thread size such as 1/8 inch NPT. For OEM analyzer skids with DN15 or DN25 pipe connections, we can supply flanged or tri-clamp versions.
Why Silver Automation Instruments fits lab and OEM buyers
We are not a catalog reseller. Silver Automation Instruments is a flow meter manufacturer and supplier based in Nanjing, China. We sell direct to industrial and laboratory users in Southeast Asia, Oceania, Latin America, Africa, and the Middle East. Many customers are 10 to 100 person companies that need technical contact with a factory, not just a shopping cart.
Our team can pre-configure calibration certificates, wiring diagrams, and dimensional drawings before shipment. QC reports include actual calibration data against a NIST-traceable reference. That documentation matters for ISO 17025 labs and for OEM analyzer builders who must validate their supply chain.
FAQ: Aalborg Instruments flow meter sourcing
Can you replace an Aalborg GFC mass flow controller directly?
In most cases yes. You need to confirm the flow range, gas type, inlet and outlet pressure, and command signal. Common command signals are 0 to 5 VDC or 4-20 mA. We can match the mechanical connection and pin output.
What is the accuracy of your thermal mass flow meters?
Standard accuracy is ±1 percent of full scale. Repeatability is ±0.2 percent of full scale. For low flow below 10 sccm, we can supply a high precision calibration option.
Do you offer meters for aggressive liquids in analytical labs?
Yes. For acids like HCl or sodium hypochlorite, we use PTFE lined electromagnetic flow meters or oval gear meters with PTFE gears. You need to specify concentration and temperature.
What is the typical lead time for a lab flow meter?
For common thermal mass flow meters and small oval gear meters, lead time is 5 to 10 working days. Coriolis meters may take 2 to 3 weeks. We ship by DHL, FedEx, or sea freight based on your destination.
Can you provide calibration certificates and material certificates?
Yes. We include a calibration certificate with each flow meter. Material certificates for wetted parts are available on request. Specify this when you send the inquiry.
