Pulsar Process Measurement Ltd design, manufacture and market level, volume, open channel flow, pipe flow and pump control instrumentation. Our company specialises in non-intrusive measurement, and our technology is used in a wide variety of industries and applications worldwide. By concentrating on the development of ultrasonic level measurement, we believe that Pulsar can be fairly described as the world technology leader in this field. The product range has been designed to provide a full range of alternatives, from single point of measurement installations right through to complex multi-point applications with digital communications. The ultrasonic range has been augmented with other products, so for the water industry, interface monitors for tricky sludge level measurement application have been added together with units that can be used to warn of pump failure. In more general level applications, single point measurement devices are available where continuous level measurement is inappropriate.

Pulsar dBMACH 3 - The best a flow application can get!

New from Pulsar Process Measurements is the dBMACH 3 ultrasonic transducer for the non-contacting measurement of open channel flows on water treatment works and in industrial effluent measurement applications.

With the dBMACH 3 and Pulsar's amazing new Ultra 3 and Ultra 5 control units, high accuracy in open channel flow applications has never been easier to achieve.

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 it's 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 its 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 to 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)
