Company Profile

Flowmeters & Controls: Global Supplier of Fluid Measurement Technology

Quick Answer: Silver Automation Instruments supplies flow meters and process instruments for industrial users and distributors in Southeast Asia, the Middle East, Latin America, Africa, and Oceania. Send your pressure in bar, temperature in °C, pipe size in DN, and flow range for a concrete model and price quote. We cover electromagnetic, Coriolis, ultrasonic, vortex, oval gear, thermal mass, pressure transmitters, and paperless recorders.

Silver Instruments runs a focused product line for fluid measurement and control. The company does not try to sell every instrument on the market. Here is the thing: industrial buyers want a supplier who knows the exact model after one email. We stock and support the types that engineers actually specify in oil and gas, water and wastewater, chemical, food and beverage, and marine projects.

Electromagnetic Flow Meters for Water, Wastewater, and Chemicals

Electromagnetic flow meters work when the liquid conductivity is at least 5 µS/cm. They are not for pure oils or gases. But for water, wastewater, acids, caustic, and slurries, they perform well. We offer sizes from DN15 up to DN2000. Common liners include PTFE and hard rubber. Output options include 4-20 mA HART, pulse, and RS485 Modbus. A water utility in the Philippines replaced a failing mechanical meter with a DN300 electromagnetic unit. That unit has run without maintenance for two years.

Coriolis Mass Flow Meters for Oils, Chemicals, and Batching

Coriolis meters measure mass flow directly in kg/h. They also read density and temperature in one pass. That direct mass signal helps with custody transfer, batching, and dosing. We keep DN15 to DN150 options for flows from a few kg/h to over 100000 kg/h. A paint manufacturer in Vietnam uses a DN25 Coriolis meter to dose solvent into a batch reactor. The unit has 4-20 mA HART output and ATEX Zone 1 certification. In practice, the Coriolis meter removes the need for separate density meters.

Ultrasonic, Vortex, and Thermal Mass Flow Meters

Ultrasonic flow meters cover clean water, seawater, and cooling loops. Clamp-on versions mount on existing pipes from DN20 to DN3000. We have quoted seawater flow meters for desalination plants in the Middle East and Australia. Vortex meters handle steam, compressed air, and light hydrocarbons. Thermal mass meters work well for air, nitrogen, and biogas at low flow rates. Last year a customer in Vietnam asked about a seawater flow meter for a desalination plant and needed a clamp-on unit because the line was already built. We supplied a meter with 4-20 mA HART and RS485.

Oval Gear Flow Meters for Diesel and Fuel Oil

Oval gear meters are simple positive displacement devices. They fit fuel oil, diesel, lubricants, and some solvents. Most engineers specify them when the flow is steady and the pipe size is small. We supply DN15 to DN80 oval gear meters with pulse or 4-20 mA output. A distributor in Brazil keeps stock of our oval gear flow meter for diesel because local truck fleets and generator users ask for it monthly. Price depends on body material and seal material.

Pressure Transmitters and Paperless Recorders

Pressure transmitters complete the measurement loop. We offer ranges from -1 bar to 1000 bar with 4-20 mA HART output. Body materials include 316L stainless steel and Hastelloy for aggressive media. Paperless recorders accept 4-20 mA, thermocouple, and PT100 inputs. They log 6 to 24 channels and export data over USB or Ethernet. A chemical plant in Thailand uses our pressure transmitters on reactor jackets and a 12 channel paperless recorder to archive batch data. So the instrument package stays clean and audit ready.
