Interface level detection — what to consider
19 March, 2009 | Supplied by: Endress+Hauser Australia Pty Ltd
Compared to standard level measurements in liquids, the detection and measurement of interfaces has its own particular challenges, leaving many interface applications without reliable level measurement. Most popular today are the electronic or non-mechanical solutions with no moving mechanical parts which offer much higher long-term stability and low-maintenance operation.
Passive sonar flowmeter technology — operating principles
18 March, 2009 | Supplied by: KROHNE Australia Pty Ltd
Flow measurements in the mineral processing and mining industry suffer from the limitations placed by previously available flowmeters including the commonly used instruments such as ultrasonic meters, magmeters, turbine meters, orifice plate meters, vortex meters, Coriolis meters and Venturi meters. The desire or requirement to make a non-contact measurement that is accurate and robust, and can be performed on practically any type of fluid within practically any type of pipe, has driven the creation of a new class of flowmeters.
Data acquisition system

Pressure controllers and gauges
15 March, 2009 | Supplied by: CMC Technologies Pty Ltd
The Series A3 digital differential pressure controller is a microprocessor-based pressure controller for positive, negative and differential pressure as well as velocity and flow. The Series A3 differential pressure controller includes two 8A SPDT relays and an associated software package that allows full configuration of variables such as set points, dead band, engineering units and flow coefficients. The programming is done from a user-friendly menu on the LCD or uploaded using an Opti Link programming key. The LCD also displays the exact set points or other user-defined variables during normal operation. The menu structure can be customised by moving variables to different menu levels to accommodate many applications.
Silo level measurement

The Silopilot FMM20 is an electromechanical level measuring device featuring an uncomplicated but rugged construction that is unaffected by silo geometry, dust, temperature, low dielectric values and static electricity. The simple-to-operate Silopilot FMM20 is suitable for use in bunkers and silos holding light bulk solids such as wheat, plastic granules and powder.
Piezoelectric accelerometer
13 March, 2009 | Supplied by: Applied Measurement Australia
The Measurement Specialties model EGPE-2A is a piezoelectric charge mode accelerometer designed for high-frequency vibration and shock measurements.
Thermal mass flowmeter
12 March, 2009 | Supplied by: AMS Instrumentation & Calibration Pty Ltd
The ST75 flowmeter from Fluid Components International is now available in a remote mountable configuration for applications in hazardous areas or hard-to-reach locations. The ST75’s remote mount transmitter, which includes a full digital display, can be mounted up to 15 m away from its thermal mass flow sensor in the process piping and connected via two 0.50" FNPT cables.
Swagelok flowmeters
12 March, 2009 | Supplied by: Swagelok
Swagelok variable area flowmeters (VAFs) are used to measure liquid and gas flow rates by means of a tapered tube and float, and provide highly accurate measurement with individually calibrated scales and a 10:1 turndown ratio. All Swagelok VAFs are factory calibrated and marked to indicate the specific media, flow range, and accuracy class. In addition, the product can be calibrated and marked to customer-specific applications.
