Pulsar Process Measurement Ltd
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 helps Heathrow work out the Time of Flight
Pulsar Process Measurement, ultrasonic level measurement specialists based in Malvern, have supplied three IMP units to a critical flow measurement application at Heathrow, the UK's biggest and busiest airport.
Heathrow employs 70,000 people directly, handling more than £50 billion worth of cargo and 63 million passengers per year, so it has to operate at peak efficiency. A major airport covers a huge area, and when it rains, generates a lot of run-off surface water. At Heathrow, the majority of this water drains through three 1.4m diameter circular pipes, with flow rates that can vary between 10 l/sec and 1000 l/sec. Discharge is to river, treated through a reed bed. BAA, the site owner, is required to maintain a record of discharge flow volumes.
The main contractor, Flowline, supplied time-of-flight flowmeters to measure the velocity of the flow in the pipes. The time-of-flight system depends upon an accurate measurement of the velocity of flow within the pipe and of the level (head) of the water. Ultraflux meters handled velocity measurement, which was integrated with the level signal produced by the Pulsar IMP units to calculate the flow rate.
Pulsar's IMP is a self-contained non-contacting ultrasonic level unit, simply installed and calibrated to give a reliable and consistent measurement of level. The sophisticated echo processing software installed makes IMP ideal for both solids and liquids applications.
Flowline now solely fits Pulsar equipment for non-contacting level measurement. As Mark Davis of Flowline puts it: "we need equipment we can rely on to integrate into our systems. The Pulsar IMP units all read within 1mm of each other straight out of the box, that gives us confidence that we can trust them to work well for us".
