The BTU07 is a full featured and low cost BTU meter with Modbus over RS485 capability developed specifically for sub metering applications. The DFSR737A is unique among BTU meters by having the BTU calculator separate from the flow sensor, which allows the flow meter to be installed where it is needed, but with the BTU calculator and display installed anywhere it is convenient for tenant reading. The BTU07 comes as a set together with the flow and temperature sensors.

The AMR (auto meter reading) is an I/O module that has been specifically designed for the special needs of auto meter reading applications. The AMR can be interfaced directly with the output of various types of pulse output meters (electricity, water, gas, BTU) and the data collected from the various meters sent to a central host via its RS485 interface. Some special features which distinguish it from regular I/O modules are:

– noise filtering from the pulse input to prevent miscounts

– EEPROM memory to retain count data in case of power interruption

– accommodates up to 16 channels of pulse input

– dry contact channel input that eliminates the need for additional power supply

– synchronize retain count with actual meter display

– rechargeable battery backup option to maintain at least 8 hours of continuous operation during a power outage

Introduction To Building Management Systems

A BMS is most common in a large building. Its core function is to manage the environment within the building and may control temperature, carbon dioxide levels and humidity within a building. As a core function in most BMS systems, it controls heating and cooling, manages the systems that distribute this air throughout the building (for example by operating fans or opening/closing dampers), and then locally controls the mixture of heating and cooling to achieve the desired room temperature. A secondary function sometimes is to monitor the level of human-generated CO2, mixing in outside air with waste air to increase the amount of oxygen while also minimising heat/cooling losses.

Systems linked to a BMS typically represent 40% of a building\\\’s energy usage; if lighting is included, this number approaches 70%. BMS systems are a critical component to managing energy demand. Improperly configured BMS systems are believed to account for 20% of building energy usage, or approximately 8% of total energy usage in the United States.[citation needed]

As well as controlling the building\\\’s internal environment, BMS systems are sometimes linked to access control (turnstiles and access doors controlling who is allowed access and egress to the building) or other security systems such as closed-circuit television (CCTV) and motion detectors. Fire alarm systems and elevators are also sometimes linked to a BMS, for example, if a fire is detected then the system could shut off dampers in the ventilation system to stop smoke spreading and send all the elevators to the ground floor and park them to prevent people from using them in the event of a fire.

Functions of Building Management Systems

The three basic functions of a central, computer-controlled BMS are:

• controlling

• monitoring

• optimizing

the building’s facilities, mechanical, and electrical equipment for comfort, safety, and efficiency.

A BMS normally comprises of:

• Power systems

• Illumination system

• Electric power control system

• Heating,Ventilation and Air-conditioning HVAC System

• Security and observation system

• Magnetic card and access system

• Fire alarm system

• Lifts, elevators etc.

• Plumbing system

• Burglar alarms, CCTV

• Trace Heating

• Other engineering systems

• Home Automation System

• Fire alarm and Safety system

WebCTRL® Environmental Index™

Balancing Efficiency with Comfort

As energy prices continue to soar, facility managers are under increasing pressure to find ways to cut building operating costs. A simple solution would be to decrease energy consumption, but smart managers know that sacrificing comfort for energy savings could lead to even bigger financial problems. After all, studies have shown productivity decreases as comfort levels decline, leading to lost revenues in companies and difficult learning environments in school systems. What’s needed is a way to measure comfort, so managers would know exactly how far to cut energy usage without negatively impacting comfort. Automated Logic’s Environmental Index provides the solution. Since the key component of comfort is temperature, ALC’s index starts with assigning point values based on the difference between zone temperature and heating and cooling set points. Other factors, such as humidity and CO2 levels, can also be computed into the numeric system to reflect one “comfort” score for all factors. This is a powerful tool for facility managers who need to identify buildings with performance problems or ensure buildings don’t become less efficient as changes are made.
