ULTRA 4 Non-contacting, ultrasonic, level control & flow measurement. Offering On-Screen Trend Monitoring in a Compact, Cost-Effective Package Ultra 4 offers the sophistication and advanced features of the rest of the Ultra range in a compact, cost-effective package and useful 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 losing none of the easy setup and configuration that has made the Ultra range of controllers the natural choice for non-contacting measurement worldwide. Features & Benefits Like the rest of Pulsar Measurement’s ‘transducer plus controller’ ranges, Ultra 4 is compatible with both dB Ultrasonic and dBR Radar transducers. The unit can be either wall or fascia mounted, allowing it to be used in a wide range of applications all over the world. THE RIGHT METER FOR • Pump Control • Open Channel Flow & Level • Chemical Dosing • IBC Tank Level • Storage Tank Levels • CSO & Sewer Network Monitoring Communications & Data Logging Ultra 4 includes Profibus and Modbus RTU digital communication options, enabling high accuracy, non-contacting measurement with communications in one multifunctional controller. The convenience of an on-board micro SD card slot for extended data logging makes storing, accessing, and analyzing data that little bit easier. Three Different Device Settings in One Convenient Controller The Ultra 4 from Pulsar Measurement can dedicate the functionality of the unit to any of three specific duties e.g. level or volume measurement, pump control, or flow measurement. Despite its high specification and ability to combine these measurements, the Ultra 4 has been designed so that blending these functions does not lead to complicated calibration and a compromise to the product specification. Functional Qualities The controller sends a transmit pulse to the transducer, which emits an ultrasonic pulse or radar signal — as this controller is compatible with BOTH radar and ultrasonic, it doesn’t matter which transducer you choose. This signal is perpendicular to the transducer face and the returned echo is sent back to the Ultra 4. The time taken PUL SAR

to receive the echo is measured and the distance from the transducer face to the surface being monitored is calculated. The unit can measure from zero to 40 m (131.2 ft) from the face of the transducer to the surface being monitored, dependent on your application and your chosen transducer. Ultra 4 Fascia Unit The relays can be programmed to activate alarms, pump starters, or other control equipment. There is an isolated 4-20mA output that can be connected to a recorder or PLC, to monitor, depending on your chosen application. Level, space, distance, OCM head, OCM flow, or volume can be set...
