No matter if offshore in rough seas or in production in pharmaceutical cleanrooms — the ecoflow diaphragm metering pump has established itself worldwide in a range of different industries as a reliable and economical metering pump. It features an exact metering rate and enormous durability in extreme operating conditions. Low life cycle costs and high energy efficiency complete the profile of a true all-around talent.

Automatic Fire Detection Systems An automatic fire alarm system is designed to detect the unwanted presence of fire by monitoring environmental changes associated with combustion.

In general, a fire alarm system is classified as either automatically actuated, manually actuated, or both. Automatic fire alarm systems are intended to notify the building occupants to evacuate in the event of a fire or other emergency, report the event to an off-premises location in order to summon emergency services, and to prepare the structure and associated systems to control the spread of fire and smoke.

Depending on the protocol used, a Signalling Line Circuit can monitor and control several hundred devices. Each SLC polls the devices connected, which can number from a few devices to several hundred, depending on the manufacturer. Large systems may have multiple Signalling Line Circuits.

Radio Control Systems Radio Fire Alarm Systems are designed to help fire system installers and fire system engineers remove the need for hard wire fire systems and are simple to install. Packed with features that leave most "hard wired" conventional systems behind, these Radio Fire Alarm Systems offer true addressable information with almost total user control over set-up and operation.

Radio Fire Alarm Systems are an answer to fire protection of major construction sites where wired options may pose a significant problem due to the difficult and challenging installation environment.

Radio Alarm Fire Systems are an ideal solution; as control panels, call points, beacons and sounders can be quickly and inexpensively moved as each construction Piping system designs in refineries and fit out phase is completed.

There is no need to install and continually move expensive fire-rated cable. Aspirated Air Sampling Systems An aspirating smoke detector ASDconsists of a central detection unit which draws air through a network of pipes to detect smoke. The sampling chamber is based on a nephelometer that detects the presence of smoke particles suspended in air by detecting the light scattered by them in the chamber.

In most cases aspirating smoke detectors require a fan unit to draw in a sample of air from the protected area through its network of pipes, such as is the case for Wagner, Safe Fire Detection's ProSeries and Xtralis ASD systems.

Aspirating smoke detectors can detect smoke before it is visible to the human eye. ASD design corrects shortcomings of conventional smoke detectors by using sampling pipe with multiple holes.

The air samples are captured and filtered, removing any contaminants or dust to avoid false alarms and then processed by a centralized, highly sensitive laser detection unit. If smoke is detected, the systems alarm is triggered, and signals then are processed through centralized monitoring stations within a few seconds.

The result is continuous protection, every second of the day, every day of the year. Unlike other alarm signalling services, Redcare both alerts the ARC when it detects a line cut AND provides encryption to prevent the substitution of equipment or "spoofing" emulation of line conditions.

This is why Redcare is the most secure system of its kind. Gas Leak Detection Gas leak detection is the process of identifying potentially hazardous gas leaks by means of various sensors.

These sensors usually employ an audible alarm to alert people when a dangerous gas has been detected. Common sensors used today include Infrared Point Sensor, Ultrasonic gas detectors, electrochemical gas detectors, and Semiconductor Sensors.

More recently, infrared imaging sensors have come into use. All of these sensors are used for a wide range of applications, and can be found in industrial plants, refineries, wastewater treatment facilities, vehicles, and around the home.

Although historically only used in factories and large commercial buildings, systems for home and small building are now available at a cost-effective price. Fire sprinkler systems are extensively used worldwide, with over 40 million sprinkler heads fitted each year.

Renewed interest in and support for sprinkler systems in the UK, largely as a result of effective lobbying by the National Fire Sprinkler Network, the European Fire Sprinkler Network and the British Automatic Fire Sprinkler Association has resulted in sprinkler systems being more widely installed.

In schools, for example, the government has issued recommendations through Building Bulletin that most new schools should be constructed with sprinkler protection. In Wales became the first country in the world where sprinklers are compulsory in all new homes.

A fire hydrant is an active fire protection measure, and a source of water provided in most urban, suburban and rural areas with municipal water service to enable firefighters to tap into the municipal water supply to assist in extinguishing a fire.

Buildings near a hydrant may qualify for an insurance discount since firefighters should be able to more rapidly extinguish a fire on the insured property.LEWA ecoflow ® diaphragm metering pump.

Its sophisticated modular system makes the ecoflow diaphragm metering pump the correct industrial pump for almost all applications. The first theoretical analysis of the behaviour of pipe bends when subject to a bending moment was made by Theodore Von Karman, who showed that when curved pipe is subjected to a bending moment in its own plane, the circular cross section undergoes changes and is .

Absolute pressure: pressure is measured in psi (pounds per square inch) in the imperial system and kPa (kiloPascal or bar) in the metric timberdesignmag.com pressure measurements are made relative to the local atmospheric pressure.
