Technologies

For over 40 years, MACE has been designing and manufacturing water flow meters, data loggers and sensors. Flow metering technologies that MACE has developed and utilised include Doppler Ultrasonic, Transit-time Ultrasonic, and Electromechanical.

All this experience culminates in the launch of our XCi range of flow meters and data loggers. The XCi multiple card interface provides our customers with a flexible platform to connect a wide range of sensors to meet their exact monitoring requirements.

And now with MACE WebComm you can access your data remotely from an XCi device via a 3G/GSM mobile network.
Our core team of research and development engineers are focused on providing customer driven products that are both easy to use and withstand the test of time in often remote and harsh environmental conditions. Indeed, as a result of over 40 years continued emphasis on product development, MACE remains a world leader in flow metering.


Doppler Ultrasonic Flow Measurement

MACE Doppler ultrasonic sensors transmit an ultrasonic (sound) wave into the flow. This sound wave is reflected by acoustically reflective particles (e.g. air bubbles, suspended solids) and the instrument detects the reflected frequencies. The difference between the transmitted frequency and the received frequencies is directly proportional to the velocity of the stream flow.

In full or partially full pipes, the velocity of the stream flow varies markedly across the cross-section of the pipe. Typically, velocity is zero along the wall of the pipe and increases to a maximum at or about the centre of the pipe. MACE Doppler ultrasonic sensors receive reflected frequencies from particles moving at these different velocities. The greater the area of flow moving at a particular velocity, the greater the number of reflections with the respective frequency shift. The average velocity of the stream is therefore calculated by averaging those frequency reflections received across the whole stream profile.


MASP (MACE Advanced Signal Processing)

MACE Doppler ultrasonic velocity sensors utilizing MACE Advanced Signal Processing (MASP) technology “see” across the entire stream profile to give a true average velocity even with extreme turbulance or reverse flows. Therefore more accurate readings are recorded by MACE sensors using this technology.

By comparison, traditional insert devices only “see” a golf ball sized point of the stream flow around the sensor head then use complex algorithms to estimate average velocity.


XCi Multiple Card Interface

The XCi (multiple card interface) allows the user to connect a vast array of water flow sensors and water quality sensors to a single XCi device. It’s a smart packaged monitoring solution that provides remote data access with alerts and alarms. It’s also telemetry-ready for effective low cost control and rapid response. Users can install any combination of the MACE cards shown, in the five available card slots.

Choose the right card/s for your application to tailor the XCi device to your exact monitoring requirements now and in the future.

ZX SnapStrap

The ZX SnapStrap was designed by MACE to easily install Doppler ultrasonic area/velocity and velocity sensors into pipes ranging in size from 225mm (8″) to 810mm (32″).

The ZX SnapStrap allows a sensor to be installed inside a pipe in minutes. The expandable Z shaped snap in the strap provides a very secure fitting inside the pipe and will not move. The tough polypropylene strap is only 2mm thick and has a chamfered leading edge so it will not cause any debris or waste to foul in the pipe.

The sensor can easily be removed and relocated to another site.
