Product Options


The SITRANS 3100 magnetic flowmeter from Siemens comes with a large variety of liners and electrode material. The magflo is also supplied with grounding electrodes as standard. These features, combined with a rugged, fully welded construction, make the 3100 magnetic flowmeter a perfect fit for almost every flow measurement application.

Various liners are available, and the 3100 magnetic flowmeter is supplied with measuring electrodes which are capable of withstanding the most extreme processes.

To create a complete magnetic flowmeter the MAG3100 should be combined with one of the following transmitters:

  • SITRANS FM MAG 5000: A cost efficient transmitter, accuracy of + 0.4 % of flow rate
  • SITRANS FM MAG 6000: Bus communication, batch function ,accuracy: + 0.2 % of flow rate


  • Flexible sensor program with several pipe dimensions available and additionally liner and electrode options
  • Approvals for PTB, OIML R 75, OIML R 117, ATEX, NSF/ANSI Standard 61, WRAS
  • Approved for hazardous areas
  • Designed to allow patented MAG in-situ verification using the SENSORPROM fingerprints

Yes, the ordering process is very easy. Orders can be made via purchase order or by credit/debit card. Once we have the paperwork we can delivery next day to any location in Europe. Provided with the equipment is a quick start guide, and if you need extra support, the technical support engineers can be contacted via phone call.
Every flow meter is tested upon shipping and return as part of our ISO9001 procedure. Also, as part of this procedure, the flow meter is calibrated once a year. If a copy of the calibration certificate is needed let us know.
We are here to help. If the self-help and quick start guides do not help, then call one of our technical support engineers on +44 (0) 1527 882060. We have supplied and supported many clamp on rental installations throughout Europe.
If the stock is permitting, and all paperwork is received by 12pm then flow meters can usually be available the next day.
Without exception, all our flow meters are tested. If you need a 110v plug instead of the standard 230v plug let us know.
As long as the pipe is relatively clean, coatings or paint is usually not a problem for clamp on flow meters but if the pipe is corroded or the paintwork has bubbled then a quick sanding down with sandpaper or a wire brush is recommended.
An ultrasonic wall thickness gauge, that measures to within 0.05mm, is provided as standard with all flow meter rental packages.
The screendump facility on the integrated dataloggers on all our flow meters, allows you to photograph any screen and download it to your pc.
