UltraTWIN Pulsar Ultrasonic Measurement

UltraTWIN Pulsar Ultrasonic Measurement

Flexibility is the UltraTWIN two channel ultrasonic system. Each channel is user-configurable to operate independently either as a full function open channel flow monitor, a pump control system or as a level and volume monitoring unit for liquids or solids, calculating volumes and providing alarms. UltraTWIN is compatiable with the full range of dB Transducers. UltraTWIN features six relays configurable to either channel.
