European Directive 2004/22/EC is aimed at harmonising the regulations and classifications in the area of water metering across Europe. With effect from 30th October 2006 it replaces all European directives and national regulations making it necessary for all water meters to meet the standard of NF EN14154 and/or recommendation OIML R49.

So what does this mean in practice? Well it changes the baseline that is used to define the metering performance of a water meter.

A water meter is now defined by:

• Q3 : Continuous flowrate
• R : Q3/Q1 ratio (where Q1 is the flowrate)

Secondary characteristics are:

• Q2 : The transition flowrate given by Q2/Q1
• Q4 : The overload flowrate given by Q4/Q3

This means that the possible values of Q3 (measured in cubic metres) and R are:

Can you still buy and fit class A, B & C water meters?

Yes for 10 years at the most as products approved before the MID (Oct 2006) were approved for a 10 year period.

DMS Flow Measurement and Controls Limited is proud to announce the 10th anniversary of the company in April of 2010.

The company started life as Direct Metering Supplies Limited but decided to rename itself during 2004 recognising that nearly all their clients had adopted the abbreviation ‘DMS.’

Over 10 years DMS have established themselves as a major supplier of Water Meters, Heat and Cooling Meters, Gas Meters, Electricity Meters and Oil Meters. They hold comprehensive stocks at their premises in Eastwood, Nottinghamshire and can despatch most orders the same day.

They have established excellent relationships with their European suppliers and are proud to represent such major names in the industry such as Sontex, Kamstrup, GWF, Apator PoWogaz, Wateau, Elster, Samgas and Tecnocontrol.

They also have a web commerce site www.dmsltd.com where a large range of products are available to order over the internet linked with an e-bay shop makes internet shopping a easy option.

DMS look forward to the next 10 years serving thier ever growing customer base.

NEW!! DMS Dynamic ultrasonic flow meter / energy meter clamp-on to the outside of pipes and do not contact the internal liquid. The technology has inherent advantages over alternate devices including: low-cost installation, no pressure head loss, no moving parts to maintain or replace, no fluid compatibility issue, and a large, bi-directional measuring range that ensures reliable readings even at very low and high flow rates. DMS Dynamic is available in a variety of configurations that permit the user to select a meter with features suitable to meet particular application requirements.

To See The DMS Dynamic Section For More Info

The DMS Dynamic is available in two versions: a stand-alone flow meter, and an energy flow meter used in conjunction with a Supercal 531 Heat Integrator. The energy flow meter measures energy usage in kWh or MWh and is ideal for retrofit, chilled water and other HVAC applications.

FEATURES

• May be used to measure clean liquids as well as those with small amounts of suspended solids or aeration (e.g., surface water, sewage).
• Bi-directional flow measurement system. Totalizer options include forward, reverse and net total.
• Modbus RTU over RS485 communications
• Ethernet connection includes BACNet®/IP
• Ethernet/IPTM and Modbus TCP/IP protocols.
• Compact enclosure uses large, easy-to-read digital display.
• Rugged, aluminum enclosure ensures a long service life in harsh environments.

BENEFITS

• Reduced material costs: clamp-on sensor eliminates the need for in-line flanges, pipe fittings, strainers, and filters.
• Reduced installation time: the DMS Dynamic may be installed and fully operational within minutes.
• Reduced maintenance costs: with no moving parts, there is nothing on the DMS Dynamic to wear down – no repair kits or replacement parts are needed.
• No need to shut down the process for installation or maintenance due to clamp-on sensor design.
