Pulsar Process Measurement has been in existence since 1997, rising in a relatively short time to become one of the foremost non-contacting level measurement instrument manufacturers worldwide. By taking a step forward in echo processing technology, Pulsar have been able to address applications previously thought to be beyond the scope of ultrasonic level measurement. In addition, by improving initial signal processing at the transducer head it has been possible to increase resistance to electrical noise, which has also increased the number of possible applications.
