PART 2 - PRODUCTS

2.1 GENERAL

A. The Energy metering solutions provides a seamless reading of the followingmeters:

1. Cooling meters2. Heat Meters3. Water Meetrs4. Electricity Meters5. Gas Meters6. Pulse based meters

B. Reading of the meters in any combination from the AMR software system can bevia:1. M-Bus2. RF Radio3. TCP/IP4. GSM/GPRS5. DLMS/COSEM6. EURIDIS7. Manual via Hand Held Terminal

In the below system overview the various reading capabilities and communicationoptions are shown.

C. System Overview

From the AMR software system data are provided in a number of formats to beexported to the Customer Information System or a bill can be generated from theThexx AMR System.

2.2 CALCULATOR

A. The MULTICAL calculator is used for heat metering, cooling metering or for

combined heat/cooling metering. MULTICAL connects to most flow sensors with

a pulse output or is supplied with flow meter ULTRAFLOW. When flow sensors

are connected in both flow and return pipes MULTICAL can also monitor possibleleakages and bursts in the system.

B. MULTICAL receives volume pulses from the connected flow sensors and

calculates energy for each predetermined water volume.

C. Energy calculation comprises temperature measurement in flow and return flowpipes and correction for specific gravity and heat content based on the

requirements in EN 1434. MULTICAL

is available with battery back-up for realtime clock and it requires as voltage supply either 230 VAC, 24 VAC or 3.6 Vlithium battery with a lifetime of up to 12 years.

D. Data reading is made either via optical reading on the front plate or via the plug-inmodules placed in the calculator.

E. The MULTICAL can be fitted with 2 individual communication modules, giving ie.

Data output to a billing system and at the same time providing data to a BMSsystem.

F. Features include:

1. Meets the specifications of EN 14342. IP 543. M-Bus interface

G. The electricity meters and Water metres shall be connected to the same calculatorto produce a combined reading for each tenant to be transferred to the AMRsoftware terminal

2.3 FLOW SENSOR

A. The flow sensor for cooling metering and heat/cooling metering is an ultrasonic

meter of the type ULTRAFLOW 65-1/T which is available from qp 0.6 m/h andup to qp 1000 m/h. The water flow is measured by means of ultrasound bysending a sound signal with the water flow and one against the water flow. Thedifference in time between the two signals is proportional to the water flow.

B. The temperature range of the flow sensor is from 2-50C. This implies that theflow sensor must be mounted in the return flow pipe in bifunctional heating/coolingsystems.

C. Calculators used for for cooling meters and heat/cooling meters must always bewall-mounted or the like to protect against condensation from the cold flow sensor.

1. Meets the specifications of EN 14342. Ultrasonic measurement principple3. 0.6 1,000 m3/h nominal flow range4. Very low cut-off flow5. High accuracy6. Low pressure drop7. Working pressure up to PN258. Additional protection against condensation9. IP65 Classified

2.4 TEMPERATURE SENSORS

A. Temperature sensors are delivered as matched pairs and are designed to provideextreme high accuracy and reliability.

B. Communication method shall be coordinated with the master system andcalculator

C. The meter shall meat the following standards:

1. EN 50470-1, EN 50470-32. International approval according to IEC 62052-11, IEC 62053-21

2.7 READING SOLUTIONS

A. The reading solutions available with The AMR systems shall include the following:

1. M-Bus2. RF Radio3. TCP/IP4. GSM/GPRS5. Hand held Terminal and RF radio

B. The site condition has a very strong TCP/IP LAN. The design shall use M-Businside each building and then use TCP/IP LAN to connect all ancillary buildings tothe Hotel and Convention Center and accounting office

C. Via M-Bus

1. The system shall offers a full range of M-Bus solutions for reading ofCooling, heat, cold water, gas and electricity meters via M-Bus.

2. The advantage of M-Bus is that the customer can read locally byconnecting a laptop to the M-Bus Master, or that the system can be remoteread with The AMR system.

3. M-Bus is a standardised reading system with a module placed in eachmeter - an M-Bus Slave which is connected to and supplied by an M-BusMaster.

PART 3 - EXECUTION
