The Pulsar new level range is deceptively simple
"Blackbox" is a newly launched component ultrasonic level measurement range from Pulsar Process Measurement, allowing users to select the output they need for their specific application
Fascia mount option for Ultra range of sensors
Pulsar Process Measurement have made all of their core "Ultra" range of ultrasonic level and flow measurement and control equipment available in a fascia-mount format
The accuracy of an ultrasonic application is in part determined by the distance that the measurement is made over, and the dBMach 3 is revolutionary in that it has no blanking distance beyond the 70mm nose cone.
That means that the dBMach 3 can be sited closer than ever to the high flow level.
The other key issue in determining the resolution of the measurement is the frequency at which the transducer emits the ultrasonic pulse, and the dBMach 3 leads the industry with a 125kHz operating frequency.
No other transducer looks like the dBMach 3 either, with its unique "solar shade" helping to reduce temperature fluctuations due to solar radiated heat.
dBMach 3 can be sited up to 1000m from its control unit, connected by a simple shielded pair cable.
In the United Kingdom, new regulations (The Urban Waste Water Directive and MCERTS) demand that open channel installations are accurate to at least +/-8%.
The new dBMach 3 helps make this possible, and in conjunction with its control unit will also measure to BS3680 when matched to a suitable primary measurement device (V-notch weir or a flume). Request a free brochure from Pulsar Process Measurement ...
