The Kamstrup MULTICAL 801 is an energy meter suited to industrial and commercial applications where the meter is exposed to extreme environmental conditions. The following text is taken from the Kamstrup press release.

Under the headline “Don’t let poor equipment get you down” Kamstrup launches the MULTICAL^® 801, an energy meter of its own class. Power supply back-up, valve control and IP67-sealing ensure precise metering of heat and cooling consumption even in dusty and moist environments.

In the commercial & industry segment metering equipment is often exposed to rough influences. MULTICAL^® 801 is a meter designed for delivering precise data even under extreme conditions.

Due to its IP67 sealing MULTICAL^® 801 is robust and capable of functioning even in dusty and moist environments. Furthermore the backlit display is readable regardless of the light conditions.

MULTICAL^® 801 is compatible with temperature sensors like Pt100 and Pt500 versions with a 2- or 4-wire connection. The capacity ranges from 0,6 to 30.000m3/h in a temperature span from 2^o C-180^o C.

MULTICAL^® 801 is based on proven technology, but a number of extra features have been added in order to meet the most demanding applications.

Back-up function

In case of power outage an internal battery maintains all basic metering functions.

Valve controller
A built-in valve controller automatically limits effect, maximum flow and temperature difference once the flow rate has been set.

Leakage control
MULTICAL^® 801 equipped with flow meters in both flow and return pipes generates leakage control and submersion surveillance on heating systems as well as cold water pipes. As another feature, impulses from connected water meters reveal leakages in the tap water system.
The intelligent warning system reduces repair costs and prevents spilling of water.
Several communication channels
MULTICAL^® 801 provides four analogue pulse outputs for remote reading via radio, GSM/GPRS, M-Bus, LonWorks or one of Kamstrup’s network solutions. MULTICAL^® 801 manages up to four communication channels.

Data loggers
All consumption data are stored for 460 days, 36 months and 15 years. MULTICAL^® 801 contains a data logging module with a programmable logging interval. This enables an accurate analysis of the energy consumption and a means for trouble shooting.

Of the highest standard
MULTICAL^® 801 is certified for the EN 1434-4:2007, the environmental class C and tested and approved according to the MID, the M1, E1, and E2. In the industrial class E2 the meter is certified for 100m cables for temperature sensors and flow meter.

Kamstrup is a world leading manufacturer of energy meters. Our energy meters are based on advanced ultrasonic measuring. Since 1991 the ultrasonic technology has been improved and refined at Kamstrup, and it has proven extremely reliable and accurate.

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.

Diaphragm Gas Meters

Samgas & Elster range of Diaphragm Gas Meters G2.5 to G100 offer a very wide measuring range designed for working upto 0.5 bar. All models are available with the option of Low Frequency pulse outputs for use with Energy Monitoring Systems. The principal elements of the meter are a pressed steel casing internally and externally coated against corrosion. A measuring module which is inserted into the casing a complete unit and a magnetic coupling transmitting the movement to the index.
 
For ‘Smart Metering’ applications Elster Diaphragm Gas Meters are also available with an m-bus interface by using the BK Z6-1 Absolute Encoder index.

Turbine Gas Meters

QA & QAe Turbine Gas Meters

QA Quantometers are highly reliable gas meters which can be used throughout the entire field of flow metering and which fulfil all of the varying requirements of industrial metering.
The QA and QAe quantometers work on the principle of the rotating turbine wheel. The rotation of the turbine wheel is proportional to the volume of the flowing gas and this volume (Vb/m3 ) is registered by either a mechanical (QA) or an electronic (QAe) index. The QA & QAe  turbine gas meters are available in sizes DN 25 (1″) to DN 150

For ‘Smart Metering’ applications the QAe Gas Meters with electronic indexes are also available which have an EN1434 m-bus interface as standard.

Q75 Short Pattern Turbine Gas Flow Meters

The Q/Q75 series of quantometers are well known in the field of industry and commerce as robust and accurate turbine meters. They have a low price and are particularly suitable for highly-accurate and reliable metering, also in higher flow and pressure ranges.

The Q75 is available in sizes DN 50 to DN 600

Roots Rotary Positive Displacement Meters

The ROOTS© meter is designed to accurately measure the total volume of dry gasses and gas mixtures. The time tested and accepted ROOTS© meter with its permanent accuracy employs the rotary positive displacement principle. This built-in accuracy is fixed by precision machined impellers and a rigid measuring chamber. Measurement is not affected by changes in gas specific gravity of pressure nor by wide fluctuating flows. The ROOTS© meter is available in sizes DN 50 to DN 200

CPT Turbine Gas Meters

The CPT Quantometer is a turbine gas flow meter based on the rotation of an impellor, the speed of rotation being proportional to the flow rate of the gas. A magnetic linkage transfers this movement to the mechanical index, which provides an accurate reading of totalized gas flow and a scaled pulse output for remote reading etc. The meters are constructed for installation between flanges like a “sandwich”. The index head can be rotated through 350 degrees. The CPT  turbine gas meter is available in sizes DN 50 to DN 200

The Tecnocontrol range of products cover single to multi-zone applications with a large coverage of gases the central controllers can be wall or panel (front or DIN rail) mounted.

To compliment the gas detection range there is a range of auto or manual gas safety valves all with a closed position switch option for BMS control.
