Flow Technology Flow Meter Catalog: High-Precision Sizing Solutions for Critical Oil and Gas Lines
Quick Answer: Silver Automation Instruments supplies high precision flow meters sized for critical oil and gas lines. You can choose Coriolis, ultrasonic, vortex, oval gear, or thermal mass meters depending on the fluid and operating conditions. Send us pressure, temperature, pipe size, and flow range and we will return a model selection with a quote.
We build meter selection around oil and gas field realities. That means high pressure, dirty flow, fast transients, and remote sites. A wrong meter size creates measurement error or early failure. Our team checks Reynolds numbers, viscosity in cP, density, and line size before quoting. Our selection process follows the same logic used in a flow technology flow meter catalog. That means no guesswork on pressure drop, line size, or material compatibility.
Meter Selection for Oil and Gas Lines
Coriolis mass flow meters cover most critical liquid and gas batching jobs. They read mass flow directly in kg/h. They also output density and temperature. For crude oils, fuel oils, LPG, and chemicals, a Coriolis meter with 316L stainless steel wetted parts handles pressures up to 413 bar. Sizes start at DN15 and go to DN300.
Ultrasonic flow meters suit large pipelines and custody transfer points. Clamp-on versions install without cutting the line. Inline versions handle clean liquids and gas. We often quote ultrasonic meters for refined product lines in Southeast Asia and the Middle East. No moving parts means less maintenance in remote desert or offshore locations.
Critical Sizing Inputs
Most engineers skip this part. They send a pipe size and a rough flow range. Then the meter arrives and does not perform. We ask for more detail. In practice, a DN80 line can carry many different mass flows depending on density and pressure. Tell us the fluid type, operating pressure in bar, temperature in °C, pipe size in DN, minimum and maximum flow rate in kg/h or m³/h, and viscosity if the fluid is high cP or non-Newtonian.
Here is the thing. A Coriolis meter must handle the lowest flow rate without losing accuracy. A vortex meter must avoid low flow dropout at high turndown. An oval gear meter must match viscosity in cP or the internal clearance causes slip. We have seen this on customer sites many times.
Specific Meter Options and Recommended Models
For heavy crude or bunker fuel, we specify a Coriolis mass flow meter with PT100 temperature measurement and 4-20 mA HART output. It works in ATEX Zone 1 areas when ordered with the right housing. DN25 to DN100 covers most loading skids. Accuracy is often ±0.2 percent of rate.
For produced water or water injection, an electromagnetic flow meter is a strong option. It handles µS/cm conductivity levels typical in oilfield water. Sizes from DN15 to DN600. The lining and electrode material must match salinity and temperature.
For flare gas or fuel gas, a thermal mass flow meter gives direct mass flow. It does not need pressure and temperature compensation. We often quote insertion thermal meters for stack and flare lines. Output options include 4-20 mA HART and Modbus.
For diesel, keros
Pressure transmitters and paperless recorders complete the loop. A 4-20 mA HART pressure transmitter gives line pressure data for mass flow correction. A paperless recorder stores flow, pressure, and temperature trends without chart paper. We supply these as part of integrated skid packages.
One Customer Example
Last year a customer in Vietnam asked us for a crude oil loading skid flow meter. They sent pipe size DN80, pressure 25 bar, temperature 80 °C, and flow rate 20 000 kg/h. We quoted a Coriolis mass flow meter with 316L wetted parts and ATEX Zone 1 approval. The meter arrived and passed commissioning with a custody transfer check. That customer now orders the same model for three more skids. So the customer avoided buying an oversized meter. He also saved on pressure drop and got stable custody transfer data.
Supply and Support
We work with SME end users and distributors in Southeast Asia, Oceania, Latin America, Africa, and the Middle East. We supply from our facility in China. Most quoted models are in stock or built within two to three weeks. But we do not stop at the meter. We also provide wiring drawings, calibration certificates, and after-sales support on WhatsApp or WeChat.

FAQ
What flow meter types does Silver Instruments recommend for critical oil and gas lines?
We recommend Coriolis mass flow meters for liquids and gas batching, ultrasonic meters for large pipelines, vortex meters for steam and gas fuel, oval gear meters for diesel and fuel oil, and thermal mass meters for flare gas. The right choice depends on fluid type, line size, pressure, and required accuracy.
What parameters do I need to send for a sizing request?
Send fluid type, operating pressure in bar, temperature in °C, pipe size in DN, minimum and maximum flow rate, and viscosity if it is high cP or non-Newtonian. We also need the output signal you prefer such as 4-20 mA HART or Modbus.
Can you supply ATEX Zone 1 or Zone 2 approved meters?
Yes. We supply meters with ATEX Zone 1 and Zone 2 approvals for gas and dust environments. We request the gas group and temperature class before quoting to make sure the model is correct.
What is the typical lead time for oil and gas flow meters?
Many standard models are in stock and ship within five working days. Custom models with special wetted parts or high pressure ratings usually ship within two to three weeks. We confirm the delivery date before you pay.
Do you support distributors in Southeast Asia and the Middle East?
Yes. We work with distributors and end users in Southeast Asia, Oceania, Latin America, Africa, and the Middle East. We provide technical data, drawings, calibration certificates, and after-sales support on WhatsApp or WeChat.
