Ultra 3 Pulsar's Ultrasonic Measurement

Ultra 3 provides reliable non-contacting ultrasonic level, volume, open channel flow measurement and pump control. The Ultra 3 controller benefits from Pulsar's DATEM, advanced echo processing software, for reliable level measurement.

Available in 4 different versions to suit your installation requirements.
