Ultra 4 Pulsar Non-contacting Ultrasonic Level Control and Flow Measurement

Ultra 4 offers the sophistication and advanced features of the rest of the Ultra range in a compact, cost effective package and useful new features that make it even easier to set up and fine-tune. Offering as the name suggests, four alarm or control relays (3 X SPCO isolated and 1 x SPNO solid state) and a multi-functional display while loosing none of the easy set up and configuration that has made the Ultra range the natural choice for non-contacting measurement world-wide.

Like the rest of Pulsar’s ‘transducer plus controller’ ranges, Ultra 4 is compatiable with both dB ultrasonic and dBR radar transducers. Ultra 4 can be wither wall or fasica mounted and includes HART, Profibus and Modbus digital communications options and the convenience of on-board micro SD card slot for extended data logging. Like the rest of the Ultra range, Ultra 4 also offers built in volume calculations based on standard tank shapes as well as advanced pump control and open channel flow measurement functions.
