Quick Answer: Krohne flow meters are built for aggressive chemicals, non-conductive oils, high solid slurries, and other difficult process media. Silver Instruments offers comparable Coriolis, electromagnetic, ultrasonic, vortex, and oval gear meters for these same applications. Send your pipe size, flow range, pressure, and temperature for a specific quote.
Many standard flow meters fail when the fluid is not clean water. A magnetic flow meter needs minimum conductivity. A turbine meter jams on solids. A differential pressure meter drifts on viscous polymer. Engineers who deal with paints, resins, brines, liquefied gas, or sludge know this.
Krohne addresses these problems with electromagnetic meters for conductive liquids, Coriolis meters for mass flow regardless of density, and ultrasonic meters for non-invasive installation. Silver Instruments supplies the same meter types with similar process connections, outputs, and certifications. We focus on practical project pricing for Southeast Asia, Australia, Latin America, Africa, and the Middle East.
Corrosive acids and alkalis: Use a PTFE or PFA lined electromagnetic flow meter. Check the conductivity is above 5 µS/cm. Most engineers skip this check until the meter reads zero. Common sizes range from DN10 to DN300. Outputs include 4-20 mA HART and pulse. Silver Instruments offers a DN15 to DN200 magmeter with PTFE liner for sulphuric acid and hydrochloric acid dosing.
High viscosity resins and pastes: A Coriolis mass flow meter measures mass directly in kg/h. Viscosity up to 50,000 cP is not a problem for many models. One paint manufacturer in Vietnam replaced a gear meter with a DN25 Coriolis meter from Silver Instruments. The line pressure was 12 bar and the flow range was 30 to 600 kg/h.
Non-conductive oils and solvents: Electromagnetic meters cannot measure these fluids. Choose an oval gear flow meter for diesel, lubricants, or solvents. Silver Instruments offers oval gear meters with 0.5% accuracy and pulse output for batching systems.
Slurries and sludge: An electromagnetic flow meter with abrasion resistant liner works well for mining slurry and wastewater sludge. A customer in Chile used a DN150 magmeter with polyurethane liner on a copper tailings line. The solids content was 20 percent by weight.
Liquefied gas and cryogenic media: Vortex flow meters with integrated PT100 temperature compensation handle LNG, LPG, and nitrogen. Silver Instruments supplies inline vortex meters with 316L stainless steel bodies and ATEX Zone 1 certification for these jobs.
Most process plants do not buy a flow meter alone. They buy a signal that can integrate with PLC or DCS. Krohne meters support 4-20 mA HART, pulse, Modbus RTU, and Profibus PA. Silver Instruments matches these protocols on our Coriolis and electromagnetic models. We also supply local indicators with totalizer functions for chemical batching.
For hazardous areas, ask for ATEX or IECEx certification. A sugar refinery in Thailand requested an electromagnetic flow meter for molasses with ATEX Zone 1 approval. We provided a DN40 meter with EPDM liner and stainless steel electrodes. The HART output connected directly to their existing PLC.
We are not a distributor for Krohne. We are a flow meter manufacturer and supplier based in Nanjing, China. Our team helps you select the right meter type, line size, liner, electrode, and output. We also handle export paperwork for Australia, Saudi Arabia, Mexico, Nigeria, and Indonesia.
Here is the thing. Many projects do not need a full re-design. If you already have Krohne flow meters on site, Silver Instruments can supply a form fit replacement with the same process connection and signal. We have seen this on customer sites many times. A plant in Malaysia kept the same flanges and just swapped the meter body. Send us the tag plate details, pipe size, fluid name, density, viscosity, conductivity, temperature, and pressure.
Contact Silver Instruments for a quote. Tel: +86-25-68650347. Whatsapp: +86-25-52155837. WeChat: +86 15365082610. Send your pressure in bar, temperature in °C, pipe size in DN, and flow range.
Can Silver Instruments replace a Krohne electromagnetic flow meter without pipe changes? Yes. We offer many DIN and ANSI flange sizes from DN10 to DN300. You need to confirm the liner material, electrode type, and output. Send us the existing meter tag data.
What is the typical delivery time for a Coriolis meter to Australia? Standard DN15 to DN50 Coriolis meters ship within 7 to 14 days. Larger models or special certifications can take 4 to 6 weeks. We ship by DHL, FedEx, or sea freight depending on size and urgency.
Do you supply flow meters for seawater desalination plants? Yes. We supply electromagnetic flow meters for brine, seawater, and permeate lines. A typical request is a DN200 PTFE lined meter with 4-20 mA HART output for reject brine. We also offer ultrasonic clamp-on meters for non-invasive checks.
Can you provide ATEX or IECEx certification for hazardous areas? Yes. We can supply electromagnetic, vortex, and Coriolis meters with ATEX Zone 1 or Zone 2 certification. Specify the gas group and temperature class when you send the inquiry.
What information do you need for a fast quote? Pipe size in DN, fluid type, flow range, pressure in bar, temperature in °C, and required output. If you have density or viscosity data, include that too. Send it by WhatsApp or WeChat to our sales team.
