Coriolis Flow Meter YouTube: Engineering Videos Explaining Mass Sizing Theory
Quick Answer: Watch engineering videos that explain mass flow sizing before you select a Coriolis meter. You need flow range, density, viscosity, pressure, temperature, and pipe size. Silver Automation Instruments supplies Coriolis mass flow meters from DN3 to DN150 with 4-20 mA HART output and direct mass flow in kg/h.
Many engineers search for Coriolis flow meter YouTube videos because mass sizing theory is different from volumetric meter sizing. A magnetic flow meter measures volume. A Coriolis meter measures mass directly. This matters when density changes with temperature or when the process fluid is not water.
In practice, most engineers skip this part. They pick a line size and assume the meter will work. We have seen this on customer sites many times. A DN50 Coriolis meter may cover a nominal flow range of 0 to 36,000 kg/h. But if your minimum flow is only 80 kg/h, a DN50 meter may lose accuracy at low flow. The sizing theory shown in good YouTube videos explains turndown, pressure drop, and zero stability.
What Mass Sizing Theory Really Covers
Mass sizing theory starts with mass flow rate. You do not convert from volumetric flow unless you know density at operating conditions. The basic formula is mass flow equals volume flow multiplied by density. For a Coriolis meter, the meter measures mass flow directly from tube vibration. The sizing exercise decides tube size, flow range, pressure loss, and accuracy.
Process temperature changes the tube material and sensor rating. High temperature sensors use Hastelloy C22 or stainless steel 316L. Viscosity affects pressure drop. High viscosity fluids like heavy fuel oil or syrup increase pressure loss through the meter. A correct Coriolis sizing calculation keeps pressure drop below 0.5 bar to 1.0 bar for most liquid applications.
A good video explains the difference between a bent tube and a straight tube Coriolis sensor. Bent tube sensors give high accuracy at low flow. Straight tube sensors drain well for food and beverage CIP processes. The video cannot replace a manufacturer calculation, but it gives you a mental model.
Sizing Inputs You Need Before You Ask for a Quote
We ask for specific data. Send us your pressure (bar), temperature (°C), pipe size (DN), and flow range. Add density at operating conditions, viscosity in cP, and the fluid name. This is not a generic contact request. These inputs let us check tube material, process connection, flow calibration, and transmitter options.
Last year a paint manufacturer in Southeast Asia asked us about a DN40 Coriolis meter for solvent blending. Their flow range was 500 kg/h to 6,000 kg/h. Density was 0.86 kg/L. Viscosity was 12 cP. The DN25 meter gave higher accuracy and a pressure drop below 0.4 bar. The DN40 meter would have worked, but tu

Common Sizing Mistakes We See on Customer Sites
One mistake is selecting a Coriolis meter by line size only. A DN25 meter from one manufacturer can have a nominal flow range of 0 to 24,000 kg/h. Another DN25 meter may have a range of 0 to 10,000 kg/h. You must compare flow range against your minimum and maximum mass flow.
Another mistake is ignoring gas applications. Coriolis meters handle gas mass flow, but gas density is low. A small mass flow rate in kg/h can mean a large volumetric flow at low pressure. You may need a larger meter than expected. YouTube videos that show air or natural gas sizing help with this.
Silver Instruments Coriolis Flow Meter Options
Silver Automation Instruments supplies Coriolis mass flow meters for liquids, gases, and slurries. Common sizes include DN3, DN10, DN15, DN25, DN40, DN50, DN80, DN100, and DN150. Process connections include tri-clamp, flange, and threaded types. Output includes 4-20 mA HART, pulse, and RS485 Modbus.
For hazardous areas, we can supply ATEX Zone 1 or Zone 2 approvals. Temperature ratings depend on the version. Standard sensors operate from -50 °C to 150 °C. High temperature versions can reach 200 °C or 350 °C depending on the model. Pressure ratings commonly go from PN16 to PN100.
How to Use Engineering Videos for a Faster Quote
Watch one or two videos on mass flow sizing theory. Note the terms turndown ratio, zero stability, pressure drop, and meter factor. Write down your process values. Then send those values to Silver Instruments. This reduces the back and forth.
Do not rely on a video to give you a final model number. A video explains the theory. A manufacturer checks the application. Use the video for education. Use our application engineers for sizing confirmation.
FAQ
Which flow range do I need for a Coriolis meter? You need the minimum, normal, and maximum mass flow in kg/h. Accuracy at minimum flow matters more than maximum flow.
Can a Coriolis meter measure gas flow? Yes. Provide gas density or molecular weight, pressure, temperature, and mass flow range. Gas sizing needs more care because density is low.
What pipe size should I select? Do not select by pipe size only. Use flow range and pressure drop. A smaller meter can often handle the same mass flow with better accuracy but higher pressure loss.
What outputs does Silver Instruments offer? Standard output is 4-20 mA HART. We also supply pulse and RS485 Modbus. We can add PT100 temperature output if the application needs it.
