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.
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.
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.
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.
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.
For hazardous areas, select an ATEX Zone 1 or Zone 2 approved transmitter. Ex d IIC T6 protection is available. Outputs include 4-20 mA HART, Modbus RTU, and pulse. The transmitter housing is IP67. This keeps the system simple for skid builders in Thailand or Indonesia.
Desalination plants in the Middle East use Coriolis meters for chemical dosing and brine density. A plant in Saudi Arabia measures antiscalant flow at 12 kg/h and brine density at 1.03 g/cm³. The direct mass reading avoids errors from temperature swings. A palm oil refinery in Indonesia uses a DN50 Coriolis meter to measure oil flow and density. The output drives separation control.
LNG and industrial gas sites in Latin America also use Coriolis meters for liquefied gas mass flow. The same sensor measures density, so the control system can detect fluid phase change. We have supplied units for a carbon dioxide dosing skid in Chile.
Mount the sensor without pipe stress. Support the adjacent piping. Do not let the meter act as a pipe support. For liquid applications, mount the meter so process fluid fills the tubes fully. For gas applications, drain any liquid slugs before startup.
Zero calibration should be done after installation. Fill the sensor with process fluid at operating temperature and pressure. Then run the zero function. Many field errors come from skipping this step. A small vibration from a pump or a nearby motor can shift the zero point. Most engineers miss this on the first site visit.
Send us your pressure in bar, temperature in degrees Celsius, pipe size in DN, and flow range in kg/h. Also tell us the fluid name, connection type, and hazardous area classification. Our sales engineers will propose a model and a transmitter option within 24 hours.

What line sizes are available? Standard sizes start at DN15 and go up to DN200. Special orders can reach DN250 for larger pipelines.
Can one meter really measure mass flow and density? Yes. The sensor measures mass flow from the Coriolis effect and density from the natural frequency of the vibrating tubes. Temperature comes from a built in PT100.
What accuracy can I expect on liquid mass flow? Expect ±0.1 percent of rate for liquids on standard designs. Gas mass flow accuracy is ±0.5 percent of rate. Repeatability is even tighter.
Does Silver Instruments offer hazardous area approvals? Yes. ATEX Zone 1 and Zone 2 versions are available. The transmitter has Ex d IIC T6 protection and IP67 housing.
How do I choose between straight tube and bent tube? Straight tube suits sanitary and low pressure drop applications. Bent tube suits very low flow rates and high sensitivity. Send us your process data and we will specify the right design.
A premium multi-variable Coriolis meter is not a commodity purchase. But the long term savings from fewer instruments and lower measurement drift often outweigh the initial price. Send your process data and we will respond with a fixed quotation.
