Product Options


The ISCO 2103G GSM/GPRS Telemetry Modem module allows the user to retrieve data and communicate remotely with a stack of 2100 series flow meters. This can eliminate the need for land-line installation, repeated site visits, and costly and often hazardous confined space entries.

The 2103G is compatible with user-subscribed GSM mobile phone services (T-mobile, O2 etc) via a standard SIM card which is placed in a waterproof port on the base of the module. Service parameters or provider can be changed by simply replacing the SIM card.

Data can be sent automatically via the internet using economical GPRS packet-switched data transmission. The data retrieval interval of between 5 minutes and 24 hours can be set by the user and the 2103G can be configured to automatically switch to a secondary interval when user set conditions are met. Isco Flowlink Pro software and an Oracle or Microsoft SQL database are needed for this functionality (contact RS Hydro for more information).

Standard Features of the 2103G telemetry modem include:

  • Communication possible wherever a GSM mobile signal can be detected
  • Automatic dial out alarm messaging to mobile phones or pagers
  • Resistant to lightning damage
  • Easy setup and service provider can be changed by installing another SIM card
  • Enclosure is NEMA 4X, 6P and IP68 rated
  • Compatible with Isco's Flowlink data management software which enables sophisticated graphing, editing, reporting, analysis and archiving
  • Extended battery life - The telemetry modem can be programmed to power up for data transmission only and power down when complete.

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.
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.
