Emerson Flow Meter Coriolis Selection Guide: Choosing the Right Micro Motion Sensor for Your Process
Quick Answer: Choose a Coriolis sensor by line size, flow range, pressure, temperature, and fluid properties. Silver Automation Instruments offers DN15, DN25, DN50, and larger Coriolis mass flow meters with 4 to 20 mA HART output. Send us your pressure in bar, temperature in degrees Celsius, pipe size in DN, and flow range in kg/h for a model and price.
Emerson Flow Meter Coriolis Selection Guide: Start With Three Numbers
Before you compare Micro Motion sensor models, collect three values. Pipe size in DN, minimum and maximum flow rate in kg/h, and fluid pressure in bar. Most engineers skip this part and then oversize the meter. Oversizing a Coriolis meter creates low flow velocity and unstable density readings.
We have seen this on customer sites many times. A buyer orders a DN50 meter because the pipe is DN50. The normal flow is only 400 kg/h. The meter reads but the low end accuracy is poor. A DN15 or DN25 meter would have been a better fit. Silver Automation Instruments supplies DN10, DN15, DN25, DN40, DN50, DN80, and DN100 models.
Match Sensor Tube Design to the Fluid
Here is the thing. A straight tube meter drains better and cleans easier. This matters in food, beverage, and sanitary systems. A bent tube meter often provides better low flow performance and is common for chemical dosing and fuel measurement. Micro Motion style sensors use several tube geometries. Silver Automation Instruments offers both straight tube and U-shaped Coriolis mass flow meters. If your product is viscous or the line is pigged, ask for a straight tube version.
For a paint manufacturer in Southeast Asia, a DN15 bent tube meter handled solvent-based coating at 80 cP without plugging. That customer switched from a turbine meter because the coating viscosity changed with temperature. Because a mass meter reads mass directly, it does not need a viscosity correction.
Review Output Signals and Hazardous Area Approvals
Many Micro Motion sensors use a 4 to 20 mA HART transmitter with Modbus or pulse output. In practice, most plants standardize on 4 to 20 mA HART for flow control. Match the output to your PLC or flow computer before you buy. Silver Automation Instruments Coriolis meters include 4 to 20 mA HART, RS485 Modbus, and pulse options. The meter uses a PT100 temperature sensor for density compensation.
For Zone 1 or Zone 2 hazardous areas, confirm the ATEX or IECEx certificate. A gas terminal in Oman needed ATEX Zone 1 and a remote transmitter. We supplied a DN50 Coriolis meter with 316L stainless steel wetted parts and a remote display. That avoided a long cable run from the skid to the control room.
Seawater, Chemical, and Food Application Notes
For seawater flow in a desalination plant, choose 316L or super duplex w
For food and beverage batching, request a sanitary connection and a polished straight tube sensor. For chemical injection, a DN10 or DN15 sensor can handle 0 to 100 kg/h of additives. Do not size the meter for the main line if the actual additive flow is low.
Price Factors and Lead Time
The price depends on line size, wetted material, transmitter type, and hazardous area certification. A DN15 Coriolis meter with 316L wetted parts and standard 4 to 20 mA HART output costs less than a DN50 meter with super duplex wetted parts and remote ATEX transmitter. Silver Automation Instruments keeps standard models for water, diesel, chemical, and food applications. If you need a very low flow meter for 0 to 60 kg/h, ask for our micro Coriolis sensor.
Send your pressure in bar, temperature in degrees Celsius, pipe size in DN, and flow range in kg/h. Our engineers will return a model number, accuracy spec, and price within one business day.
Five Questions Engineers Ask Before Buying
Can a Silver Instruments Coriolis meter replace a Micro Motion sensor? In most cases yes. Match line size, process connection, flow range, and output signal first. We provide dimension drawings for mechanical fit and 4 to 20 mA HART wiring notes.
Does a Coriolis meter work with low conductivity fluids? Yes. Coriolis meters do not need conductivity. They work for deionized water, alcohols, and oils. This is a key advantage over electromagnetic flow meters.
What is the minimum flow rate you can measure? We have a micro Coriolis sensor for 0 to 10 kg/h and standard DN15 meters for 0 to 1000 kg/h and above. Send your lowest expected flow, not just normal flow.
Can the meter handle gas entrainment? Coriolis meters tolerate small amounts of entrained gas. Heavy slug flow may cause unstable density readings. For batching applications with air pockets, install a back pressure valve or air release upstream.
What details do you need for a quote? Pipe size in DN, fluid name, viscosity in cP, pressure in bar, temperature in degrees Celsius, flow range in kg/h, output signal, and hazardous area zone. Include those details in your first email to speed up the process.
