Available from May 2010 the Kamstrup MULTICAL 402 is the successor of MULTICAL 401 – a well-known energy meter, which for long has been among the most popular meters on the market for residential and commercial applications. The following text is taken from the Kamstrup press release.

MULTICAL 402 is designed for maximum functionality and usability. On the large readable display both actual consumption, accumulated consumption and target date consumption can be shown. Extra pulse outputs for energy and volume enable easy integration into different forms of building management systems.

No battery change
MULTICAL 402 is easy to install and wear-free. The flow meter is based on ultrasonic technology with no moving parts and due to new technology and fine-tuned operation the battery supply will keep the meter running for 16 years.
A low total cost of ownership combined with accurate measurement throughout the long service life makes MULTICAL 402 a good investment.

Wireless meter reading
The new energy meter also carries extended functionality in respect to reading. Besides wired M-Bus the meter is read via wireless M-Bus – a one-way radio communication with open protocol. For this purpose Kamstrup supplies a so-called Wireless M-Bus Reader, a hand-held reading unit, which automatically collects meter data, when in physical proximity of a MULTICAL 402 meter.

Besides Wireless M-Bus Reader, MULTICAL 402 can be read wirelessly with hand-held units like USB Meter Reader and MULTITERM Pro. Furthermore MULTICAL 402 can easily be integrated into advanced radio based meter reading systems, in which data are automatically transferred to the central Meter Data Management System back at the utility.

Low environmental impact
MULTICAL 402 is the first product from Kamstrup with a Carbon Footprint report. Carbon Footprint is a term that covers the total emission caused by a product throughout its entire service life. The environmental impact of the meter, from cradle to grave, has been mapped and also with it comes to emission MULTICAL 402 is focused on low-energy.

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 sell a wide range of meters and an important part of our meter product range are electricity meters in particular the Iskraemeco single phase electricity meters and three phase electricity meters.

The Iskraemeco single phase electricity ME162 meters are OFGEM Approved for primary billing

The ME162 electronic kWh electricity meter is intended for electric energy measurement and registration in single-phase two-wire networks in households

………………………………………………………………………………………………………………………………….

MT171 3-Phase electronic meters are designed for measuring and registration of active energy in three-phase four-wire network for direct or CT connection.

………………………………………………………………………………………………………………………………….

The Cube 300 is a very low cost panel-mount 3-phase kWh and kW meter with a pulse output and accuracy better than Class 1. Its ‘Right First Time’ installation aids (kW display, CT, VT and Pulse value displays) clearly show if the meter is correctly wired and programmed.

These and other types of electricity meters are available from the wide range of stock at DMS.
