BTU Meter for HVAC Energy Saving

AKE BTU meter is used for HVAC billing system, especailly designed for chilled water system.compact heat meter used for measuring energy in heating and cooling plants in facility management systems as well as in local and district hearting systems. Available as a PN16 threader or PN25 flanged version,

it is ideal for nominal flows from 0.6 to 6 m3/h and product temperatures from 5 to 130 degrees centigrade. For use in cooling and air conditioning installations special versions are available, that are protected against condensed water.

Working Principle

A. Hardware

1.Energy meter collects the data of temperature sensor and flow meter.

2.Based on Heat Exchange principle, the system automatically integrates and transfers energy consumption to computer.

B. Software

AKE BTU Measurement System is equipped with software of strong function.

1) Real-time calculation: Real-timely calculates energy consumption, thus ensuring data accuracy.

2) Concentrated reads record from meters: Via software it remotely collects the data from metes. Automatically stores data and statistics.

3) Automatic checking: Automatic checking each point of the whole system, Auto-alarm in case of abnormality; records error(type & date & quantity).

4) Storing record: Stores records of every month (total twelve months) and detailed

information in a month;

5) Collecting fee as per different time: fee-collecting as different unit price basic on different period;

6) Managing function: Offer statistics of utilization rate of air-conditioning. Able to draw using diagram of a period, effortless to analyse.

7) Security functions: Requires different password as per operated class.

8) Metering management: Charging the total fee a user should pay with fee-information print ability. And the fee information can be copied out with different

format.

9) Extension function: Opens database, OPC interface, integrated easily.

10) Querying function: Checks status & consumption value of each metering area,

query history data conveniently and quickly, also can be queried via network

2) Characteristic
1. Large LCD display, shows 4 lines in each screen;
2. Heating, Cooling both suitable;
3. Modbus communication protocal based on RS485;
4. 4-wire PT1000 temperature sensor to make sure the accuarcy;
5. Calculates and displays total cooling,heating consumption, shows real time data such as temperature, flow rate, energy etc, besides historical data could be tracked on a daily/weekly/monthly/yearly basis;
6.Shows histrorical data with bar chart, convenient to analyze and check;
7. Can be auto setup small flowrate ignored;
8 intergration into AutoReading Meter system and BAS system available.

3) System Advantage

1. Based on Heat Exchange Principle, more reasonable and energy efficient

2. Electronic system, low effect from outside; long lifespan.

3. Simple structure, easy to install and maintain.

Energy Saving Rate

AKE C03P BTU meter is designed to measure individual energy consumption in the building where chilled water system is installed. Besides, it is also used to measure performance of energy saving system or the loss of efficiency which is directly tied to loss of revenue.

Operation mode: Heating , Cooling, Heating&Cooling

Component Description

AKE BTU meter consists of the following components:

Calculator(Model C03P-06/C03P-11)

Solid state circuitry for accurate and reliable operation with automatic compensation for water density. Receive signal from flowmeter and a couple of temperature sensors, calculate and indicate flow, temperature and energy consumption;

Flowmeter

Electromagnetic, turbine, vortex and ultrasonic flowmeter are compatible, but Electromagnetic flowmeter is strongly recommended to ensure accuracy and minimize maintenance;

Temperature Sensor Pair

4wire PT1000, fast response and high accuracy, longer wiring available for flexible installation without any effect on accuracy.
