Coriolis Mass Flow Meter Datasheet Accuracy Repeatability Density Diagnostics Specs Guide
Quick Answer: A Coriolis mass flow meter from Silver Instruments measures mass flow, density, and temperature in one device without external compensation. Liquid mass flow accuracy can reach ±0.10 percent of rate with repeatability at ±0.05 percent. Use this guide to check accuracy, repeatability, density, diagnostics, and model selection before you request a quote.
Why Datasheet Accuracy Matters Before You Quote
Engineers and procurement teams often compare only price. In practice, a cheaper meter with ±0.25 percent accuracy can cause batch errors in paint, syrup, or chemical dosing. We have seen a paint manufacturer in Southeast Asia replace a volumetric meter because temperature changes shifted the batch density. A Coriolis meter solved the problem because the output is mass based.
Silver Instruments supplies Coriolis mass flow meters in DN15 to DN150 line sizes. Standard accuracy for liquids on the SIL-CMF series is ±0.10 percent of rate. Gas accuracy is ±0.50 percent of rate across a typical turndown of 20 to 1. High viscosity fluids up to 500 cP do not require special calibration in most cases.
Accuracy Specs You Should Check First
Accuracy in a Coriolis datasheet usually appears as a percentage of rate plus zero stability. For example, a DN25 SIL-CMF meter may have a flow accuracy of ±0.10 percent of rate plus zero stability at 0.02 kg/h. At low flow, zero stability matters more. At high flow, the percentage of rate dominates.
Liquid mass flow accuracy on standard Silver Instruments Coriolis meters is ±0.10 percent to ±0.15 percent depending on pipe size and calibration option. Gas mass flow accuracy is ±0.35 percent to ±0.50 percent. Density accuracy of ±0.001 to ±0.005 grams per cubic centimeter is common on standard models. These values come from water calibration at 20 degrees Celsius and process conditions similar to your plant.
Repeatability in Batch and Dosing Applications
Repeatability is often more important than absolute accuracy in batching, blending, and dosing. Standard repeatability is ±0.05 percent for liquid flow. Density repeatability is ±0.0002 grams per cubic centimeter. Temperature repeatability is ±0.1 degrees Celsius using the built in PT100 sensor.
We have tested repeatability on a 300 kg batch of glucose syrup in a food plant. The meter returned the same dose within 0.04 percent over ten cycles. Because the Coriolis meter reads mass directly, air slugs and temperature swings have less impact than on turbine or electromagnetic meters in this duty.
Density Output and Concentration Checks
A unique part of the Coriolis meter is the density signal. The tube oscillation frequency changes with fluid density. The onboard transmitter converts this into a density value in grams per cubic centimeter or kilograms per cubic meter. Engineers use this signal for concentration measurement, quality checks, and interface detection between two products.
Typical density accuracy on the SIL-CMF series is ±0.002 grams per cubic centimeter. This density accuracy is enough for many brix or concentration applications in food and beverage. For chemical injection or custody transfer, optional calibration can improve density accuracy. The same meter outputs mass flow, volume flow, density, and temperature over 4-20 mA HART, pulse, or RS485 Modbus.
Diagnostics T
Here is the thing. Most engineers skip diagnostics until a batch fails. The Silver Instruments transmitter includes real time monitoring for drive gain, pickoff voltage, tube frequency, empty pipe, two-phase flow, and electronics temperature. If drive gain rises above the normal range, the meter may be slugging or coated. A diagnostic alarm over HART or Modbus can stop the batch before off spec product leaves the skid.
Field checks are fast. You can verify the meter zero, check the diagnostic status, and export the error log without opening the housing. Since the sensor has no moving parts and no flow obstruction, routine maintenance is low. For ATEX Zone 1 installations, diagnostics read through the same 4-20 mA HART loop, so you do not need extra wiring.
How to Select a Model from the Datasheet
Start with the flow range. A DN15 Silver Coriolis meter handles low flow from about 0.1 kg/h to 1,000 kg/h depending on pressure drop. A DN50 meter may cover 1,000 kg/h to 50,000 kg/h. Check the pressure rating, usually PN40 or PN63 standard, and the process temperature. Standard units operate from minus 50 degrees Celsius to 200 degrees Celsius.
For seawater desalination, specify 316L stainless steel or super duplex wetted parts. For chemical dosing with acid, consider PTFE or Hastelloy C22 options. For food and beverage, choose a hygienic body with tri-clamp connections. Always provide the minimum and maximum flow, not just the line size. The meter performs best between 20 percent and 80 percent of the nominal range.

FAQ on Coriolis Mass Flow Meter Datasheet Specs
What accuracy can I expect for liquid mass flow? Standard accuracy is ±0.10 percent of rate for liquids on most Silver Instruments Coriolis meters. Some larger line sizes or difficult fluids may be ±0.15 percent. Gas accuracy is usually ±0.50 percent.
Is repeatability the same as accuracy? No. Repeatability is the ability to return the same output under the same conditions. Accuracy includes absolute deviation from the reference. Repeatability for liquid flow is ±0.05 percent, which is why batch systems stay stable.
How does density measurement help in chemical or food plants? The density output lets you track concentration in real time. It detects product changeover, checks brix or solids content, and flags water in oil or cleaning solution in product lines.
What diagnostics are built into the transmitter? The standard diagnostic set covers drive gain, pickoff voltage, tube frequency, empty pipe, two-phase flow, and temperature. Alarms are available over HART, Modbus, or the local display.
What information should I send for a fast quote? Send fluid name, viscosity in cP if known, flow range in kg/h, pressure in bar, temperature in degrees Celsius, pipe size in DN, and hazardous area requirement such as ATEX Zone 1 or Zone 2.
