Coriolis Flow Meter Designs: Premium Multi-Variable Mass and Density Measuring Systems

Quick Answer: Silver Instruments supplies premium Coriolis flow meter designs that measure mass flow, density, and temperature from one sensor. Standard line sizes run DN15 to DN200 with liquid mass accuracy of ±0.1 percent of rate. Send us your pressure in bar, temperature in degrees Celsius, pipe size in DN, and flow range in kg/h for a fixed quotation.

Buyers often ask which design is best. The answer depends on your fluid, line size, and installation space. Silver Instruments offers straight tube and bent tube designs. Straight tube meters drain cleanly and suit sanitary food or pharmaceutical lines. Bent tube meters handle low flow better on small pipes.

What Multi-Variable Output Actually Means

A premium Coriolis flow meter does more than totalize flow. It measures mass flow directly. It also calculates volume flow, density, and process temperature. This reduces the number of instruments on a skid. You do not need a separate density meter or a separate RTD. One process connection gives you mass total, density value in kg/m³, and temperature in degrees Celsius.

We have seen this work on a concentrated juice line in Australia. The plant replaced a turbine meter and a standalone density analyzer with one Coriolis meter. The maintenance team cut calibration hours by half. The density signal also triggered automatic brix correction in the control room.

Design Types And When To Choose Each

Straight tube designs have no bends. They drain easily and handle liquids with suspended solids more safely. Food plants use them for sauces, syrups, and dairy. The pressure drop is low. The sensor is easy to inspect.

Bent tube designs include U tube and S tube shapes. They are more sensitive at very low flow rates. A micro bend meter on a DN15 line can measure 0.1 kg/h of additive. Chemical dosing systems in Vietnam use this design for catalyst injection. The trade off is a slightly larger footprint and higher pressure drop than straight tube.

In practice, most engineers skip the geometry debate and focus on process conditions. For fluids with viscosity above 500 cP, straight tube designs reduce pressure loss. Many edible oil and syrup lines operate at 200 to 2,000 cP. Silver Instruments helps you match design to fluid viscosity, gas entrainment, and cleanability.

Measurement Ranges, Accuracy, And Model Mapping

Standard Coriolis meters from Silver Instruments cover flow rates from 0.1 kg/h to 500,000 kg/h depending on line size. Liquid mass flow accuracy is ±0.1 percent of rate. Gas mass flow accuracy is ±0.5 percent of rate. Density accuracy is ±0.0005 g/cm³. Temperature accuracy is ±0.5 degrees Celsius using a PT100 element. Turndown ratio can reach 50:1. Repeatability is ±0.05 percent.

For low flow dosing, the SICM-015 model works on a DN15 line and measures 0.1 kg/h to 100 kg/h. For main process lines, the SICM-050 on DN50 covers 100 kg/h to 15,000 kg/h. Larger units like the SICM-100 handle up to 100,000 kg/h. Share your flow range and our engineers will map the exact model.

A chemical distributor in Mexico saved 1.2 percent on raw material costs after switching to mass based batch control. The plant no longer had to compensate for temperature swings. The same meter gives the control system a direct mass total and a live density reading.

Wetted Materials, Connections, And Pressure Ratings

Standard wetted parts use 316L stainless steel. For aggressive fluids, Silver Instruments offers Hastelloy C22, titanium, and tantalum options. Process connections include tri-clamp, DIN 11851, ANSI flange, and threaded types. Pressure ratings go up to 100 bar for certain designs. Fluid temperature can range from minus 50 to plus 200 degrees Celsius.
