The Kofloc 6800 backpressure valve is a kind of relief valve that keeps the pressure at the front stage of a valve constant. It can easily and quickly control the pressure of a tank with a large buffer and remove the constant fl ow of a mixed gas, which cannot easily be done by general regulation valves with a subsequent stage controlling function. This new concept of pressure regulation has been attracting much attention.

Applications

• Tank pressure control
• Constant flow control of mixed gas

Kalinsky differential pressure gauge / differential pressure transmitter DMG5 was developed for supervising overpressure of cleanrooms.

A differential pressure sensor range +/- 50 Pa, red LED-display, alarm-lamp, signal horn, analogue output 0-10 V and 4-20 mA for connection with data logger, 2 switching outputs with adjustable threshold value and an additional circuitry to store the alarm message at increasing pressure in the normal range after fall back of the threshold value of the switching output are included.

By using of a red button at the front its possible to reset the alarm message. A software controlled signal damping for display and switching outputs can selected by 10 steps.

Aichi Tokei's governors are actively working at various locations for energy-saving, labor-saving on energy control, and providing safe supply of gas.

The ones introduced here are Aichi Tokei's standard governors

• Governor for high temperature gas
• Governor with the precise adjustment handle
• Governor for gas that contains sulfide
• Other special governors

The flow meter for gas mixing uses a KOFLOC multiple flow meter to mix multicomponent fluids. Connection of pipes to respective gas inlets and the mixed gas outlet permit gases to be mixed. This flow meter is ideal for easy gas mixing in laboratories and studies.

If gases escape through leaks in piping systems (e.g. untight screwed connections, corrosions and so on) ultrasonic noises are generated. By means of LD 400 even the smallest leakages which cannot be heard by the human ear can be detected even from distances of several meters. LD 400 transforms the inaudible signals into a frequency which can be identified. By means of the comfortable sound-proof headset these noises can be realized even in extremely noisy environments.

Due to a particularly designed acoustic trumpet a better focusing of the acoustic waves is achieved. This acoustic trumpet acts like a directional microphone while interfering ambient noises are cushioned and the accurate localization of the leakages is eased even in areas which are difficult to access.

Kent Elster Helix Woltmann cold water meter can be installed in horizontal, vertical or inclined pipelines without loss of accuracy. This meter not only conforms to relevant BS, ISO and EEC standards, but offers user benefits which greatly exceed these specifications.

The Kofloc mass flow controllers and meters, which measure the mass flow rate, are less influenced by the temperature and pressure as compared with mechanical flow meters and valves, and can electrically exchange information about the flow rate. They are used in a wide range of processes and equipment in the fields where high levels of accuracy, repeatability, responsiveness and cost effectiveness are required, such as semiconductors, optic fibers, various analyses, fuel cells, liquid crystal, organic electroluminescence, biotechnology, foods, environmental measurement, combustion gas control, plant facilities and examination equipment.

It is simple to use this Dickson pressure logger PR125, PR325, PR525, PR120, PR320 to record and integrate pressure data into documents and spreadsheets, giving results a professional, polished look. When fulfillment of regulatory requirements or accurate recording of pressure for quality control is needed, this logger is the perfect instrument.

Dickson Pressure Recorder PW4 and PW8 series comes with weather-resistant case-- the outdoor pressure monitoring solution of choice

Electromagnetic flow meters detect flow by using Faraday's Law of induction.

Inside an electromagnetic flow meter, there is an electromagnetic coil that generates a magnetic field, and electrodes that capture electromotive force(voltage). Due to this, although it may appear as if there is nothing inside the flow pipe of an electromagnetic flow meter, flow can be measured.

Oval gear flowmeters are categorised as positive displacement flow technology. When liquid flows through this type of positive displacement flowmeter, two oval geared rotors measure a constant volume per rotation within a precisely machined measuring chamber.

With each rotation, a constant volume of liquid is measured. The rotation of the oval gears is sensed via magnets embedded within the rotors. These magnets transmit a high resolution pulse output. The output signal can be process externally via a remote display controller or PLC or via a variety of output/display options available as accessories attached to the flowmeters.

The positive displacement flow technology allows for precise flow measurement of most clean liquids regardless of the media conductivity. Other liquid properties also have a minimal effect on the performance of this type of meter. Flow profile conditioning is not required as with alternative flow technology options making oval gear installations simple to install in tight spaces and at an economical price.

Aichi Tokei Turbine gas meters TBZ and TBX series, developed to measure gas consumption of a small boiler, an individual furnace, or other individual gas equipment, are achieved to have high accuracy consists with the light-weighted compact stylish body.
They can widely correspond to maximum working pressure and maximum measuring flow-rate.
The built-in 2-systems pulse transmitter allows your configuration of a remote reading system or of an advanced energy management system. Also, TBZ series even offers temperature / pressure compensation function that is to display gas consumption converted to its volume at the standard conditions (0,1 atms ), etc.

Whisper Ultrasonic Leak Detector is ideal for detecting and locating sources of ultrasonic sound through the use of sophisticated electronic circuitry. Unaffected by audible noise, Whisper incorporates an Internal Noise Control allowing for use in extremely noisy environments, such as mechanical rooms, and around operating chillers. Because Whisper is designed to detect ultrasound at 40.5 kHz, not even a murmur will escape detection.
