Refrigerant Flow Meter Manufacturer: Sourcing Factory-Direct Hardware with Global Specs
Quick Answer
Silver Instruments supplies factory-direct Coriolis mass flow meters for liquid refrigerants. These meters measure mass flow in kg/h with 0.2 percent accuracy, independent of fluid density or temperature. You bypass distributor markups and get global certifications like ATEX, IECEx, and CE as standard. Send us your refrigerant type, pressure, pipe size, and required flow range, and we return a full quote within one business day.
Why Coriolis Meters Drive Refrigerant Measurement
In refrigeration systems, compressors, condensers, and evaporators depend on precise refrigerant charge. A small overcharge or undercharge can slash energy efficiency by 10 to 15 percent. Turbine and positive displacement meters drift when fluid properties shift. Coriolis technology is different. It directly reads mass flow and density. No need for separate temperature or pressure compensation. When you work with R134a, R410A, R32, or R290, the meter stays accurate even during rapid phase changes.
Many HVAC labs and production lines use Coriolis meters for refrigerant charging and recovery. We have seen customers eliminate 5 to 8 percent of refrigerant waste just by switching from volumetric measurement. The Silver CF Series handles liquid viscosities from 0.5 cP up to 200 cP, so heavy lubricant mixtures do not choke it. This is a real advantage for ammonia-based systems where oil carryover is common.
Factory-Direct Supply Without the Middleman
Most industrial OEMs and contractors buy flow meters through local distributors. That adds 25 to 40 percent to the final price. Silver Instruments runs a factory-direct program from our Nanjing, China calibration center. You get the same hardware as big integrators but at ex-works rates. We ship to Southeast Asia, Oceania, Latin America, the Middle East, and Africa every week. Our logistics partners include DHL, FedEx, and sea freight forwarders for full container loads. You can request door-to-door delivery or pickup from our warehouse.
A cold storage builder in the Philippines needed 12 refrigerant flow points for a multi-compressor ammonia system. Local quotes averaged AUD 4,200 per meter with a six-week lead time. Silver Instruments delivered calibrated Coriolis meters with ATEX Zone 2 certification at AUD 2,650 each. Lead time was three weeks air freight. The project stayed on budget, and the engineer told us the zero stability was better than the European alternative. Because we manufacture in-house, we also do not charge extra for stainless steel 316L wetted parts or Hastelloy options on small orders.
Global Specifications That Match Your Site
Different countries demand different certifications. Our refrigerant flow meters ship with CE, UKCA, ATEX Zone 1 or Zone 2, IECEx, and PED compliance as needed. For the Middle East, we supply meters with 24 V DC power, RS485 Modbus RTU output, and IP67 enclosures because outdoor chiller plants are harsh. In Latin America, we include PT100 temperature output and 4-20 mA HART for direct connection to local PLCs. Many Australian and New Zealand customers favor pulse output for charging machines. The meter body is a compact twin-tube design, available from DN3 to DN50. Larger sizes up to DN100 can be quoted for big ammonia lines. Accuracy remains ±0.2 percent of rate, with repeatability of
Every meter leaves the factory with a 5-point water calibration certificate traceable to ISO 17025. For special refrigerants, we can calibrate with silicone oil or actual R134a at an additional cost. But most customers use standard water calibration and then apply the built-in density factor. The onboard transmitter handles the conversion.
Installation Tips from Real Sites
Engineers often ask about straight pipe runs. A Coriolis meter needs zero upstream and downstream straight pipe. That is a big space saver in packaged chiller frames. However, you must avoid two-phase flow unless the meter is sized correctly. If your refrigerant flashes inside the tube, measurement noise increases. In practice, install the meter after the condenser and receiver where the liquid is subcooled. A paint manufacturer in Malaysia learned this the hard way when they placed a turbine meter too close to the expansion valve. They switched to our CF-015 model and moved the sensor 2 meters upstream. Flow stability improved immediately.
Another common scenario is refrigerant recovery on shipboard systems. A marine chiller OEM in Singapore needed an IP68 rated meter for a vessel destined to the North Sea. We customized the CF-025 with welded joints and a 316L junction box. They now order 30 meters a year under a blanket agreement. That arrangement works well for repeat business; we hold safety stock for key clients.
How to Request a Quote

FAQ
What is the best flow meter for liquid refrigerants?
Coriolis mass flow meters are the preferred choice. They measure mass flow directly, ignore density variations, and provide the high accuracy required for refrigerant charge control.
Can your meters measure refrigerant gas?
Yes, the Coriolis meter works on gas phase if the density is above the sensing threshold. However, for pure gas measurement, thermal mass flow meters or vortex meters might be more cost-effective. Tell us your phase condition.
Do you provide ATEX certified refrigerant flow meters?
Absolutely. We supply ATEX Zone 1 and Zone 2 intrinsically safe versions for ammonia and hydrocarbon refrigerants. The certification covers Ex ia IIC T4 Ga.
How long is the delivery time to Australia?
Typical air freight to Sydney or Melbourne is 7 to 10 working days. Sea freight takes 4 to 5 weeks but saves cost on bulk orders. We provide tracking from the Nanjing gateway.
What maintenance does a Coriolis refrigerant meter need?
There are no moving parts. Annual zero-check is recommended. If the process fluid leaves residue, flush the tubes. Otherwise these meters run for years without drift.
