Pulsar IMP+


Non-contacting ultrasonic measurement
The IMP+ non-contacting ultrasonic sensor is designed to be used wherever you need an accurate and reliable level measurement. Its digital echo processing means the IMP+ is perfect for slurries, liquids, or anywhere you need a display telling you the level or analog output to interface with your site control system or drive a display.

There are several measurement ranges available from 200 mm to 10 m (7.9 in to 32.8 ft) and each can be wired for 2 or 3-wire operation. All options feature an LCD display and digital temperature measurement and compensation. When combined with Pulsar’s PC Suite, users are able to download, analyze and store echo profiles, set up the IMP’s parameters, install the new firmware to your IMP, and add a flow curve to be able to configure level to flow linearization.

Ultrasonic Level / Volume Control

Pulsar Ultrasonic Level Transducers Pulsar PM

Ultrasonic dB Transducer Series

Non-contacting sensors for level, volume and flow
The dB ultrasonic range of transducers ranges from 3 m (9.8 ft) measurement range right up to 50 m (164 ft) measurement range and provide a reliable level, volume, open channel flow, pump control, and differential measurement, within both liquid and solids applications. The sensors benefit from highly accurate and repeatable ultrasonic technology and a low power design with standard interconnecting cables - producing extremely high acoustic power to give exceptionally high results in a wide variety of challenging applications.

The non-contacting design of the transducer means they can be fitted with zero interruption to service, and there’s no time-consuming maintenance needed. We offer a wide range of options for our transducer range to suit the application. For example, a shield can be fitted during manufacturing to keep the transducer face clean and dry in applications at risk of submergence, PVDF versions of transducers are available for applications where there are chemicals present, and many more.

All dB Ultrasonic Transducers and dBR Radar Transducers are retrofittable with the Pulsar controller range, so if the needs for your measurement change, your measurement system won’t have to.

Pulsar Ultra Twin

Ultra Twin

Twin-channel ultrasonic measurement with the ability to combine applications 
The UltraTWIN offers an opportunity to combine ultrasonic level/volume monitoring, pump control, or open channel flow measurement in a 2-channel ultrasonic system. Each channel is user-configurable to operate independently either as a full-function open channel flow monitor - calculating flow rates, a pump control system, or as a level and volume monitoring unit for liquids or solids - calculating volumes and providing alarms.

A powerful data logging solution can be added to the UltraTWIN system, offering Pulsar’s PC Ultra Log Software which records and charts data and trends in an easily accessible form. The controller may also be upgraded to include RS485 communications, Modbus, or Profibus DPV0 or V1 protocols.

Pulsar Greyline PSL 5.0

Pulsar Greyline PSL 5.0

Hybrid Pump Station Level Controller
The Greyline PSL 5.0 Pump and Lift Station Level Controller is ideal for sewage pump stations, lift stations, wet wells, and tank level control with a non-contacting ultrasonic sensor mounted above the liquid. The PSL 5.0 Level Controller has six independently programmable control relays for pump or valve control, level alarms, dialers, temperature alarm, and echo-loss alarm.

Mount the non-contacting, ultrasonic sensor in the tank or wet well and install the watertight electronics in the control room or any location within 150 m (500 ft). Use the simple menu system and built-in keypad to set up measurement range, relay set points, and pump alternation sequence. A relay/pump run time report is updated and stored automatically for viewing on the PSL 5.0 backlit LCD display.

For hazardous locations, the ultrasonic sensor is rated intrinsically safe with an optional safety barrier. It is rated for measurement ranges up to 10 m (32 ft), or use the optional PVC Sensor rated for 15.6 m (50 ft) measurement range.

Dual-Technology Sensor Feature for Redundant Level Monitoring
Connect a submersible pressure sensor or other 4-20mA level transmitter to the PSL 5.0 for fail-safe hybrid sensing. The PSL 5.0 will auto-calibrate the redundant sensor and if the signal is lost to the ultrasonic sensor, the redundant sensor will seamlessly take over monitoring until the signal resumes from the ultrasonic. The redundant sensor is continuously monitored to ensure availability during primary sensor failure.

Sludge Finder

Pulsar Sludge Finder 2 and Viper Transducer

The Sludge Finder 2 is used in thousands of applications worldwide to detect sludge blanket levels in primary, secondary, and tertiary settlement tanks either with stationary or traveling bridges, clarifiers, gravity thickeners, or sequencing batch reactor (SBR) systems. The two-part system includes a purpose-built self-cleaning Viper Transducer that uses sonar technology, submersed into the liquid, and detects the echoes from the material. Any distinct change in density is reflected to the transducer – the time taken for the echo to return is transmitted to the controller and the distance to the interface is calculated.

The Sludge Finder 2 offers a wealth of different options depending on the application requirements, including single or dual sensor inputs, installation accessories, communication outputs, and PC Software Suite that offers Sludge Finder 2 software that can be used to record and save all the parameters from your sludge blanket level measurement applications.
