Product Options


The MASS 2100 DI 1.5 Coriolis mass flow meter is suitable for low flow measurement applications of a variety of liquids and gases. A "plug & play" mechanical and electrical interface makes installation easy and ensures optimum performance. The mass flow meter offers superior performance in terms of flow accuracy,density accuracy and turn-down range and delivers true multi-parameter measurements i.e.: Mass flow, volume flow, density, temperature and fraction.


The coriolis mass flow meter consists of a single bent tube in a double omega pipe configuration, welded directly to the process connectors at each end. The mass flowmeter is available in two configurations: AISI 316L or Hastelloy C22 with ¼" NPT or ¼" ISO process connections. The enclosure is made in stainless steel AISI 316L W 1.4404 with an encapsulation rating of IP65/NEMA 4.

The coriolis mass flow meter is available in either a standard version with a maximum liquid temperature of 125 °C (257 °F) or a high-temperature version, with raised electrical connector for 180 °C (356 °F). The mass flowmeter can be installed in either a vertical or horizontal position. It also has an enclosed single quick release clamp fitting, and this combined with its compact design and single multi-plug electrical connector keep installation time and costs to a minimum


  • High flow accuracy (better than 0.1% of mass flow rate)
  • Densitometer performance available through a density accuracy better than 0.001 g/cm3 with a repeatability better than 0.0002 g/cm3
  • Large dynamic turn-down range better than 500:1, from 65 kg/h to a few g/h
  • Has a single continuous tube design that with no internal welds, reductions or flow splitters. This offers optimal hygiene, safety and CIP cleanability for applications in the food & beverage and pharmaceutical sectors.
  • Balanced pipe design with little mechanical energy-loss, ensures optimal performance and stability under non-ideal and unstable process conditions (pressure, temperature, densitychanges etc.)
  • 4-wire Pt1000 temperature measurement ensures optimum accuracy on mass flow, density and fraction flow
  • The market's biggest wall thickness ensures optimal life-time and corrosion resistance and high-pressure durability
  • Multi-plug electrical connector & SENSORPROM enables true "plug & play". Installation and commissioning in less than 10 min.
  • Intrinsically safe EEx ia design as standard
  • Sensor pipe available in high-quality AISI 316L stainless steel W 1.4435 or Hastelloy C22 W 2.4602 offering optimum corrosion resistance
  • Dual-drive pick-up and driver construction facilitate ultra low weight pipe construction giving the market's smallest and most stable zero point
  • The sensor calibration factor is also valid for gas measurement
  • Rugged and space-saving sensor design in stainless steel matching all environments
  • High-pressure program as standard

No, all of our flowmeters are competitively priced and rental is an ideal option for cutting costs to a fraction of a full priced new flowmeter.
No problem. The quick start guide is designed to make installing the flow meters a simple task. Everything you require for set up will be found in the peli-box supplied with the flowmeter.
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.
The flow meters typically provide an accuracy of ±1 to 2% of rate, so if you are measuring 100l/sec then the accuracy is between 98-102l/sec.
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.
First, contact us for a quote. If you are happy with the quote then send us a purchase order. Or alternatively call us with credit card details and fill out and send us a rental agreement form.
If the stock is permitting, and all paperwork is received by 12pm then flow meters can usually be available the next day.
The minimum hire period for flow meters is one week.
Once you have the meter you can rent it for as long as you need it. However, it would help if you can let us know that you wish to extend the rental period. Upon return the meter is off-hired and once checked and tested, an invoice will be issued to you. Also, if you extend your rental past a 4, 8 or 12 week rental threshold, then you are entitled to a discount.
You are only charged for the period of time for which you have the flowmeter. So, if a flowmeter is returned 3 days late you are only charged for 3 extra days, and each of these days is charged at one fifth of the weeks hire cost.
Normally, you will use your own courier but if you have any problems let us know and we can arrange a pick up the day after you notify us, but you will be charged for the carriage and this cost will be added to the invoice.
Without exception, all our flow meters are tested. If you need a 110v plug instead of the standard 230v plug let us know.
All of our standard transducers will do -40degC to +150degC, but this will depend on your application.
  • Liquid: below 50mm CFLP transducers are required, 50-1000mm CRS-402 transducers and 150-8000mm CRS-401 transducers. All the bits you need can be supplied, and delivered with the meter.
  • Gas: below 80mm CRS-402 is required, for 80-300mm the CRS-401/CRV-310 and for above 300mm the CRW-312 transducers are required.
  • High temperatures: For liquid we can measure +450degC for liquid and for gas/steam +250degC. But please consult RS Hydro.
Of course, we make a small surcharge for each set of transducers. Most applications only require one set, but on occasion some people may require two, for more diverse pipe sizes and applications.
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.
After the equipment has been shipped, it is the responsibility of the hirer. However, in our experience it is rare that any of our flow meters are damaged. Our flow meters are tough, as well as accurate, and reliable.
We have hired more ultrasonic clamp on flow meters than any other company in Europe. We are now one of the world's largest distributors of GE Panametrics flow meters. We always review your application before hire so no unwanted surprises are encountered. Every effort has been made to make your flow meter hire and enjoyable experience: quick start guides to help you set up with ease, online videos for further help, rugged packaging for extra durability anywhere, and real flow engineers available for online/telephone support.
