Picomag – The compact alternative to a mechanical flowmeter

No moving parts, simple to install, maintenance free, high performance and future proof outputs at a price much less than a mechanical float or turbine meter sounds to good to be true, but now it’s a reality.

Simple configuration via Bluetooth or IOLink reduces dramatically any commissioning time and installation couldn’t be easier. A physical footprint so small by conventional offerings means you can hold even the 2” meter in your hand.

Works with any water-based liquid with a conductivity > 10uS/cm2 and at no extra cost measures temperature and conductivity giving you multi-variable monitoring capability.

We think we should also mention, for a measurement sensor, it looks pretty good too. Think about it, ‘What’s your reason not to change!’

21st Century Flowmetering essential features

Auto-rotatable display field:

Up to 4 variables displayed (Flow, Totalisation, Conductivity and Temperature), the display field rotates automatically depending on the installation position and flow direction. This means that the values are always easy to read.

SmartBlue App: For easy commissioning in the field:

The app allows for configuration as well as comprehensive access to device data. The device communication works via Bluetooth on IOS and Android devices.

  • Simple and easy to navigate allowing quick access to device and diagnostic functions
  • Wireless configuration/data retrieval for configuration of display outputs, flow direction, units, etc
  • Up to 10m separation making those difficult to assess installations not so difficult anymore.

IO-Link For seamless integration into your plant:

At some stage, you will probably be thinking of capturing all your data and implementing a smart sensor strategy. Even if you’re not ready now, thanks to the IO-Link connection which is a standard feature, Picomag will be ready when you are to integrate seamlessly into any communication and process automation system:

  • Compatible with all standard fieldbus systems
  • Comprehensive remote data access
  • Simple set up, no additional technology tools
  • Automatic configuration after device replacement
  • Simple wiring connections
  • Future Proof - Industry 4.0 ready

Picomag – The no compromise, No options, future proof Flowmeter solution for water based liquids.

Instructions state that 2 volts is 0 flow, so when flow starts, the voltage measurement is added to the 2 volts. Correct? How do I verify that the flow meter is still measuring accurately?

Asked by: BlairK
Thank you for your inquiry about the Picomag. You are correct, at ZERO flow rate, it will output 2 Volts and if you increase the flow rate, the voltage will vary and accurately measure accordingly.

What conductivity range does the meter measure over/what does the accuracy look like?

Asked by: Anonymous
Thank you for your inquiry. The Picomag requires the liquid to have at least 5 microSiemens to measure accurately and if more conductive then require, it will still work and measure as per the published specs.

How many analog outputs are there in this device? Can I get all three - flow, temperature and conductivity as 4-20mA analog out?

Asked by: ANAG
Thank you for your inquiry on the Picomag. There are only 2 selected outputs that the flow meter can re-transmit, only 3, and can be any 2 out the 3 parameters listed in the data sheet.

Does this flow meter work for wastewater (Item# DMA15-AAAAA1)?

Asked by: bslo
Thank you for your inquiry on the Picomag flow meter. Since it does not have any moving parts, it can be used in waste water applications.

If using this sensor with a pulsating flow, what would the expected response time be? How adjustable is the damping?

Asked by: LKOA
Thank you for your inquiry. Unfortunately, ideally, the Picomag is best used for constant, pressurized flows, not intermittent or pulsations.

Can this flow meter be used for viscous fluid like polymer?

Asked by: harry20
Thank you for your inquiry! These flow meters are well suited for viscous fluids. The major concern is the conductivity of the process liquid. A minimum conductivity of 10 microsiemens per centimeter is required.

What does the pressure drop vs flow rate curve look like?

Asked by: Justine
Thank you for your inquiry. Magnetic flow meters have very low pressure drop and it is less than 1 PSI across the flow range.
