Up to 50m measurement range is available via an optional 'modified' Ultra 3 controller which powers a dB50 transducer. Includes pre-programmed tank shape conversion for a variety of standard tank shapes. Unusual shapes are also accommodated through the 32 point linearisation function.
Pump control:

Ultra 3 give you pump control on changing level or rate of level change to provide:
Power on delay
Pump start delay
Fixed duty assist
Fixed duty back up
Alternate duty assist
Alternate duty back up
Duty back up and assist
Service ratio duty assist
Service ratio duty back up
FOFO (alternate first on first off duty assist)
Open channel flow:

Ultra 3 provides flow measurement and control in a wide range of flumes and weirs by calculating flow from the measured head preceding a primary element. Flow calculation to BS ISO 1438 and 4359.
Ultra Wizard

Ultra Wizard is an on-board, menu-driven software tool that allows the user to quickly and simply set up an Ultra 3 unit for a specific application. The user is led into a 'Quick Setup' menu specific to the application chosen that allows parameters such as empty and full distances and alarm/control relay settings to be entered. The majority of applications will be 'ready to go'. This unit can also be configured using Pulsar's PC Suite software.

Applications:
Level and Volume measurement
Pump control
Open channel flow measurement
Liquids and solids measurement
Food, pharmaceutical, chemical, power generation and many more industries

Non-contacting ultrasonic level control and flow measurement

Ultra 5 product image
Ultra 5 provides flexible and reliable non-contacting ultrasonic level and volume measurement, advanced pump control and measures open channel flow to BS ISO 1438 and 4359. Ultra 5 is available as a wall, panel, fascia or 19" rack mount (visit our mounting options page for more information).
An optional Radio Telemetry System may be fitted to the Ultra 5 controller which has a 3km (1.86miles) line-of-sight range. Up to 48 Nodes can be used using a 'Multihop' receiver installation.
Advanced Ultra Range Features

Ultra 5 offers the same features as the Ultra 3 controller but also with the added benefit of more advanced features:
Level and Volume:

Ultra 5 is perfect for the wide range of level measurement applications, featuring five control relays and a measurement range from 125mm to 40m. Offers optional 4-20mA input for a pressure transmitter or similar. Includes pre-programmed tank shape conversion for a variety of standard tank shapes. Unusual shapes are also accommodated through the 32 point linearisation function.
Pump control:

Ultra 5 give you advanced pump control functions including:
Power run-on
Pump exercising
Start point variation
Storm control feature
Aeration control
Flush valve control
Differential:

Ultra 5 offers the inclusion of differential level capability using two transducers. With one upstream and the other downstream of a screen or penstock, an alarm or control signal is initiated as the difference between the level exceeds a user-defined limit to automatically operate the cleaning mechanism.
Open channel flow:

Ultra 5 provides non-contacting, flow measurement and control in a wide range of flumes and weirs with 2 additional relays.

Twin-channel ultrasonic measurement with the ability to combine applications

UltraTWIN
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.
A full-function flexible combination instrument

Level/Volume:

UltraTWIN in level/volume mode will calculate volumes based on a wide variety of standard tanks shapes measuring liquids and solids.
Pump Control:

UltraTWIN provides a wide range of sophisticated pump control routines. UltraTWIN also includes four digital inputs, making it possible to monitor the performance of other equipment, for example a no-flow signal from a pump can trigger an alarm without the need for a PLC.
Open Channel Flow:

In open channel flow mode, UltraTWIN gives you the full power of Pulsar's flow measurement expertise, that's the reason it's the choice of wastewater companies and process industries worldwide to measure open channel flow within effluent treatment processes. Features include on-board totalisation and pulsed output. UltraTWIN provides outstanding accuracy when teamed with the high resolution accuracy of the dBMACH3 transducer.

Dual Ultrasonic Echo Transducer

DUET product image
FlowCERT and Pulsar's unique twin-transducer DUET, provides the highest accuracy non-contact ultrasonic flow measurement system available anywhere.
Pulsar MCERTs certificationOnly DUET features Pulsar's unique, patented, approach the the issue of accuracy when temperature and echo reflection time varies. Both transducers fire together. By continuously monitoring the phase difference of the echoes, and because the distance between the transducer faces is known and constant, the speed of sound is continuously updated in real time on the process. The resulting accuracy and stability is exceptional.

Applications:

Non-contacting ultrasonic open channel flow measurement
