About Pulsar Ultra 3
Ultra 3 is three units in one.
Ultra 3 is a brand new concept in ultrasonic level measurement. Within its memory are all the functions and settings of three different and completely separate ultrasonic devices.
Pulsar Ultra 3 Ultrasonic Measurement provides a 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.
The Ultra 3 does not offer a multiple range of functions blended together which lead to complicated calibration and a compromise to the specification, Ultra 3 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.
Benefits
- A most versatile system which is quickly configurable to offer anyone three separate functions within seconds. Ideal for simplicity of purchase and off the shelf spares.
- A totally dedicated device with the ability to perform all aspects of the task required i.e. no compromise in specification.
- Easy to set up using the unique “Quick Set Up” Menu. To calibrate, first set the Ultra Wizard for the desired task, and then refer to the relevant
- For Level or Volume,
- For Pump Control
- For Flow open channel
Functions
Ultra 3 sends a transmit pulse to the transducer, which emits an ultrasonic pulse perpendicular to the transducer face, and the returned echo is sent back to the Ultra 3. The time taken to receive the echo is measured and the distance from the transducer face to the surface being monitored is calculated.
Ultra 3 can measure from zero to 40m from the face of the transducer to the surface being monitored, dependent on the application chosen and transducer used.
The relays can be programmed to activate alarms, pump starters, or other control equipment. There is an isolated 4-20 mA output that can be connected to a recorder or PLC, to monitor, depending on application chosen, level, space, distance, OCM head, OCM flow or volume, independently from that shown on the display. There is an RS232 port, so
that the Ultra 3 can be operated remotely by a PC or other equipment.
Ultra 3 can be programmed either by the built-in keypad (standard on all wall and fascia units), or by PC via the RS 232 Serial Interface (optional). The optional rack and panel mounted units are programmed with the Remote Communicator, and one Communicator can program many Pulsar
Ultra 3 units. All parameters are stored in non-volatile memory, so are retained in the event of power interruption. A second backup copy of all parameters can also be retained in the Ultra 3 memory, in case an alternative set of parameters needs to be stored.
Three user definable control relays with individual setpoints and intelligent performance logging software features ensure maximum control versatility.
The system utilises the unique DATEM software (Digital Adaptive Tracking of Echo Movement). This is a proven digital mapping technique developed especially for the Pulsar Ultra range, which gives the system unequalled ability when identifying the “true target level” in the face of competing echoes from pipes, pumps or other obstructions. Coupled with the powerful, long-range abilities of the ‘all new’ dB transducer range, the Ultra 3 lives up to its reputation as the most reliable ultrasonic level measurement system available.
The Pulsar Ultra 3 ultrasonic level controller has been designed to provide
maintenance-free fit and forget performance.
