Pulsar Process Measurement is an English company that has been in existence since 1997, rising in a relatively short time to become one of the foremost non-contacting level measurement instrument manufacturers in the world. 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 widened the number of possible applications.
