Bronkhorst Coriolis Mass Flow Meter Sourcing for High Accuracy Sub Gram Dosing
Quick Answer: A Bronkhorst Coriolis mass flow meter is a solid reference for sub gram dosing. But many buyers face long lead times and high cost when sourcing low flow models in Southeast Asia or Latin America. Silver Instruments supplies a Coriolis mass flow meter alternative for dosing skids with flow ranges from 0.05 kg/h to 100 kg/h. DN15 and DN20 sensors come with 4-20 mA HART output, PT100 temperature compensation, and optional ATEX Zone 1 certification.
Why Sub Gram Dosing Needs a Different Meter Selection
Sub gram dosing is common in flavor and fragrance batches, catalyst injection, coating additives, and pharmaceutical intermediate mixing. A paint manufacturer in Vietnam adds about 0.4 grams of rheology modifier per batch. The dosing time is under 10 seconds. A standard DN25 Coriolis meter was too slow to stabilize. The plant switched to a smaller DN15 sensor with PT100 temperature compensation. The batch weight error dropped from 1.2 percent to 0.35 percent of target dose.
Most engineers skip this part. They select a Coriolis meter by line size only. For sub gram dosing, sensor volume and zero stability matter more than pipe diameter.
Bronkhorst Coriolis Mass Flow Meter Sourcing Pain Points
Bronkhorst Coriolis mass flow meter models have good low flow specifications. The sensor performance is not usually the issue. The issue is availability. Distributors in Indonesia, Mexico, and the Middle East often quote 8 to 14 weeks for non stock items. Small additive producers cannot wait that long. The cost can also break the budget for a single dosing line.
In practice, the buying decision comes down to a few checks. Can the meter repeat the same dose every cycle. Can the supplier deliver within 4 weeks. Can the support team confirm the wiring before installation.
Silver Instruments Alternative for Low Flow Dosing
Silver Instruments supplies Coriolis mass flow meters sized for low flow and sub gram dosing. The typical choice is a DN15 sensor with 316L stainless steel wetted parts and a flow range from 0.05 kg/h to 100 kg/h. The transmitter outputs mass flow, density, and temperature over 4-20 mA HART or Modbus RTU. For hazardous areas, request the ATEX Zone 1 or Zone 2 certificate pack before ordering.
A customer in Chile used a DN15 Silver Instruments meter on a copper solvent extraction line. The flow range was 0.2 kg/h to 12 kg/h. The fluid was an extractant with a density of 0.92 g/cm3 and viscosity of 18 cP. The meter held a dosing repeatability of 0.2 percent of rate. The control system used the 4-20 mA HART signal to stop the pump at the exact mass setpoint.
Specs That Matter for Sub Gram Dosing
Flow range is not the only number to check. Zero stability, sensor body volume, and transmitter response time decide the low end accuracy. A DN15 sensor has less internal volume than a DN25 sensor. Less volume means less fluid dwell time and faster batch cuts. The transmitter update rate should be at least 10 Hz. The analog output should be active, not passive,
Temperature compensation matters because many dosing lines move from 20 °C to 60 °C. A PT100 sensor built into the tube wall helps the meter correct mass flow when process temperature shifts. Pressure rating matters too. Most dosing lines run at 4 bar to 10 bar. A standard 316L sensor rated for 40 bar covers most cases.
Pricing and Delivery for Sourcing Teams
We have seen this on customer sites many times. The price gap between a Bronkhorst Coriolis mass flow meter and a Silver Instruments meter can be 25 to 40 percent on the same nominal flow range. Delivery also varies. Stock DN15 and DN20 Silver Instruments meters often ship in 5 to 7 working days. Non standard flange types or special wetted materials add 2 to 3 weeks.
Because the dosing market is project driven, most buyers send a data sheet first. The data sheet should include the fluid name, density, viscosity in cP, pressure in bar, temperature in °C, pipe size DN, and target dose mass in grams per shot. Silver Instruments engineers use that data to select the tube size and confirm zero stability at the low end of the flow range.

FAQ: Bronkhorst Coriolis Mass Flow Meter Sourcing
Can Silver Instruments replace a Bronkhorst Coriolis mass flow meter on a sub gram dosing skid?
Yes in most cases. The replacement depends on tube size, wetted material, pressure, and output signal. Send the existing model code and your current process data. We will check the mechanical and electrical fit.
What is the smallest flow range Silver Instruments offers for Coriolis meters?
Our low flow DN15 sensor covers 0.05 kg/h to 100 kg/h. For gas dosing, the range is different. Tell us the fluid state and target mass per shot.
Do Silver Instruments Coriolis meters work with 4-20 mA HART and PLC systems?
Yes. Standard output is 4-20 mA HART. Modbus RS485 is optional. The analog output can be wired to a standard PLC input card with a 24 V DC supply.
What certifications are available for hazardous areas?
ATEX Zone 1 and Zone 2 options are available for many low flow Coriolis meter models. Ask for the certificate pack before shipment. The pack includes the QAR and calibration report.
How long does delivery take for a DN15 Coriolis meter?
Stock DN15 and DN20 meters often ship in 5 to 7 working days. Special orders with non standard flanges or Ex proof certificates take about 3 weeks. We will confirm the exact date when you send the full process data.
