Picomag Flow Meter: Endress+Hauser Compact Inline Electromagnetic Sensors – Industrial Review and Supply Options from Silver Automation Instruments

Quick Answer: The Picomag is a compact inline electromagnetic flow meter from Endress+Hauser built for conductive liquids. It fits tight spaces, serves small line sizes from DN 15 to DN 50, and delivers direct volumetric flow, temperature, and conductivity data. Silver Automation Instruments supplies Picomag flow meters with factory calibration certificates and a full after-sales service package for customers in Southeast Asia, Oceania, Latin America, Africa, and the Middle East. You can expect pricing from 850 to 1,350 USD depending on line size and communication protocol, and standard lead time of 2 to 4 weeks for most configurations.

What Exactly Is the Picomag Flow Meter

The Picomag is Endress+Hauser’s solution for conductive liquid flow measurement in constrained piping systems. Most engineers turn to this meter when they need a sensor with no straight pipe inlet or outlet runs. The device integrates the sensor and transmitter into a single stainless steel body. It handles liquids with a minimum conductivity of 20 µS/cm, making it practical for demineralized water, cooling water, weak acids, alkalis, and fruit juices in food and beverage lines. The Picomag uses a proven electromagnetic measuring principle and compensates for temperature changes using an internal PT100 sensor.

Many process engineers in Australia and Vietnam ask us about the device because they operate small bore tubing for coolant dosing or CIP return lines. In these applications, a full-bore magmeter is simply too large and too heavy. The Picomag weighs between 1.2 kg and 2.8 kg depending on the process connection, so it does not require additional pipe supports.

Key Specifications That Matter on Site

The standard Picomag range covers DN 15, 20, 25, 32, 40, and 50. Operating pressure goes up to 16 bar at 60 °C, and the temperature envelope extends from minus 10 °C to plus 70 °C for the compact version. Flow rates span from 0.03 m³/h up to 45 m³/h, which suits many blending skids, boiler feed lines, and small RO plant applications. The meter outputs 4-20 mA HART, a pulse, and a switch output. Some models come with IO-Link for direct integration with Rockwell or Siemens PLCs. Accuracy is ±0.5% of reading for flow when the liquid conductivity stays above 100 µS/cm, and temperature accuracy sits at ±0.5 °C.

Customers in desert climates across the Middle East often order the Picomag with an IP67 rated housing because the instrument sits in open weather near sand filters or chiller modules. The transmitter electronics are fully potted, so occasional water splash from hose-down cleaning does not cause drift.

Where Engineers Use the Picomag and Why

The Picomag shows up in skid systems, heat exchangers, cooling circuits, and water treatment dosing lines. In the food and beverage industry, one Malaysian syrup producer uses twenty Picomag units to dose glucose and fructose syrups into mixing tanks. In Chile, a lithium brine processor installed fifteen units on small-diameter leaching solution lines. The chemical industry picks the Picomag for acid dilution monitors because the PEEK liner and stainless steel electrodes can handle pH as low as 3.

Marine and offshore engineers specify the Picomag for freshwater generators and oily water separators on vessels. Because the meter works without moving parts, it withstands constant vibration from diesel generators. Oil and gas operators in Nigeria use these meters on methanol injection lines where space between bulkheads is limited.
