Picomag

Supported Applications

The Omega Picomag is a smart plug-and-play electromagnetic flowmeter designed for the reliable measurement of conductive liquids with conductivity ≥10 µS/cm. The series supports simultaneous monitoring of volume flow, temperature, and temperature-compensated conductivity. Documented applications include industrial water, cooling water, warm water, and rinsing water.

Operating Conditions & Performance

The Picomag operates within a process temperature range of -10 to +70 °C (14 to +158 °F), with temporary capability up to +85 °C (+185 °F). It is rated for a maximum process pressure of 16 bar (232 psi) and features high shock and vibration resistance, making it immune against pipe vibrations. The device carries an IP65/67 enclosure rating (Type 4).

Performance specifications vary by measured variable:

• Flow accuracy: ±0.8% o.r. or ±0.2% o.f.s. (of full scale)
• Temperature accuracy: ±2.5 °C (±4.5 °F)
• Repeatability: Flow: ±0.2% o.f.s.; Temperature: ±0.5 °C (±0.9 °F); Conductivity: ±5% o.r. or ±5 µS/cm

The series requires no inlet/outlet run (0 × DN) and is powered by DC 18 to 30 V.

Configuration Options

The Picomag series offers a compact design with a 1.4" TFT color display that auto-rotates dependent on orientation. Configuration and operation are supported via the SmartBlue App using Bluetooth wireless technology or through IO-Link for integration into process control systems.

Measurement Ranges by Nominal Diameter

• DN 15 (½"): 0.05 to 25 l/min (0.01 to 6.6 gal/min)
• DN 20 (¾"): 0.1 to 50 l/min (0.03 to 13.2 gal/min)
• DN 25 (1"): 0.2 to 100 l/min (0.05 to 26.4 gal/min)
• DN 50 (2"): 1.5 to 750 l/min (0.4 to 198.1 gal/min)

In-/Outputs and Communication

The device provides two freely selectable in-/outputs, including:

• Current outputs (4–20 mA)
• Pulse/switch output
• Voltage output (2 to 10 V)
• IO-Link
• Status inputs (e.g., for a totalizer reset)

Materials and Connections

The housing is constructed from 1.4404/316L or 1.4409/CF3M stainless steel, with the process connection made of 1.4404/316L. Wetted materials include a PEEK measuring tube, 1.4435/316L electrodes, and FKM seals.

Standard process connections are external threads (G½", G¾", G1", G2"). Optional adapter sets are available for internal (G) and external (R, NPT) threads, as well as Tri-clamp and Victaulic fittings.

Key Product Differences

The Picomag series is offered in four nominal diameters: DN 15 (½"), DN 20 (¾"), DN 25 (1"), and DN 50 (2"). The available SKUs correspond to these sizes, with model codes such as DMA15-AAAAA1 through DMA50-AAACA1. Approvals include UL listed (Underwriters Laboratories Inc.), CE mark, cUL mark, and drinking water approval (in prep.).
