Endress Hauser Flow Meters: Global Proline Series Process Intelligence Instruments

Quick Answer: The Endress Hauser Proline series covers electromagnetic, Coriolis, vortex, and ultrasonic flow meters with strong diagnostics and HART outputs. Silver Automation Instruments supplies comparable industrial flow meters for water, chemical, food, oil and gas, and marine use at lower cost and shorter lead times. Send us your process data to get a model match with a fixed price.

If you specify or buy Endress Hauser Proline instruments, you likely check Promag, Promass, Prowirl, or Prosonic models. Field engineers value the common transmitter platform and diagnostic functions. Procurement teams often worry about price, delivery, and local support in Southeast Asia, Oceania, Latin America, Africa, and the Middle East.

Silver Instruments supplies industrial flow meters to end users and distributors in these regions. We build electromagnetic flow meters, Coriolis mass flow meters, vortex flow meters, ultrasonic flow meters, oval gear flow meters, thermal mass flow meters, pressure transmitters, and paperless recorders. This guide covers the Proline models one by one and suggests a matching Silver Instruments series for each application.

Promag and Silver Instruments Electromagnetic Flow Meters

Endress Hauser Promag W and Promag P are common in water, wastewater, chemical, and food plants. They measure conductive liquids from about 5 µS/cm. Liners include PTFE, hard rubber, and polyurethane. Accuracy is 0.2 percent to 0.5 percent of reading. Outputs include 4-20 mA HART, pulse, and Modbus.

Silver Instruments electromagnetic flow meters cover DN15 to DN2000. You can choose PTFE liner, 316L electrodes, 4-20 mA HART, RS485 Modbus, IP67 or IP68 protection. We have supplied these meters to desalination plants in the Middle East, wastewater lift stations in Malaysia, and dairy lines in Australia. Conductivity must be above 5 µS/cm for a standard electromagnetic meter. Flow range and pipe material matter too.

Promass and Silver Instruments Coriolis Mass Flow Meters

Promass F, Promass A, and Promass I appear often in chemical batching, oil and gas, and food applications. They read mass flow, density, and temperature in one instrument. Accuracy is usually 0.05 percent to 0.1 percent.

Silver Instruments Coriolis mass flow meters cover DN3 to DN150 for liquid and gas mass flow. Accuracy is 0.1 percent to 0.2 percent depending on the measuring range. Process connections include tri-clamp, flange, and thread. Pressure ratings go up to 100 bar on smaller sizes. Outputs include 4-20 mA HART, pulse, and RS485. For a paint manufacturer in Vietnam, we replaced a Promass F on a solvent batch line. The process data matched the PLC. Lead time was 4 weeks. The original factory lead time was 12 weeks.

Prowirl, Prosonic, and Silver Instruments Vortex and Ultrasonic Meters

For steam, compressed air, and hot gas, the Endress Hauser Prowirl series is a standard reference. Silver Instruments vortex flow meters cover DN15 to DN300, with temperature compensation, 4-20 mA HART, and optional ATEX Zone 1 housing. For clean water and some wastewater lines, Prosonic ultrasonic meters are selected for non-contact measurement. Silver Instruments offers clamp-on and inline ultrasonic flow meters from DN25 to DN2000, with PT100 input and Modbus output.

Process Data You Should Send Before You Buy

In practice, a quote is only useful when the fluid properties and process conditions are clear. The most common missing data are conductivity, viscosity in cP, pressure in bar, temperature in °C, and pipe material. For electromagnetic meters, conductivity below 5 µS/cm creates unstable readings. For Coriolis meters, viscosity and pressure drop decide the tube size and flow capacity. For vortex meters, minimum flow velocity and vibration levels are
