Pulsar Ultra 4 & dBMACH3 Open Channel Flow with Flume/Weir Bundle

Ultra 4 is three controllers in one. It is the first-ever system to offer the ability to dedicate the functionality of the unit to any of three specific duties i.e. level or volume measurement, pump control, or flow measurement. Diagnostic trace information and measurement trending can be viewed directly on the display of the unit itself and automatically logged to SD card.

This bundle includes the Ultra 4, dBMACH3 Transducer, and PC Suite Software with dongle.

Ultra 4 Features

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.
