Nivowave
Ultrasonic level measurement with revolutionary Acoustic Wave Technology
For continuous, non contact level measurement UWT GmbH now offers the new Nivowave series -
a solution for measurement where conventional ultrasonic measuring techniques have failed.
Acoustic Wave Technology provides exact measuring results even for long distances and in difficult applications. Dust, foam and environmental noise are problems of the past.
What is the Acoustic Wave Technology?
The Nivowave series emits a high powered acoustic wave transmit pulse hence any losses have a far less effect than in conventional ultrasonic devices.
The receiver circuitry is designed to identify and monitor low level return signals even when noise levels are quite high. Thus the environment conditions do not have much influence on the evaluation of signals. High power with low frequency combined with advanced software and the use of specifically shaped cones lead to successful measurement in a wide range of applications.
Automatic modulation of sensitivity and mapping of false echoes, simple mounting and easy programming cut the costs of commissioning considerably.
The measured signal is temperature compensated to provide maximum accuracy to the outputs and display.

The ITC-9071 92 kHz air transducer is designed for a variety of ultrasonic sensor products. Its narrow beam makes it a good choice for demanding proximity, position, and level sensor applications. It can be used as a transmitter, receiver, or both as needed, and is equipped with an aluminum housing.

Bats are using this principle since a long time: sending out a sound wave and through the echoes, the distance to an object can be measured very accurate.

Nivobob – the next generation of electromechanical level measurement systems
The completely redesigned plumb bob Nivobob offers the following enhancements:
-Increased durability via brushless motor
-New rope system offers lengthened time between services
-Larger measurement distance – up to 40 metres with the tape version
For small plants that do not have their own visualisation system, an additional remote box is a well priced solution that allows up to 10 instruments to be remotely controlled. Measurement results can be viewed as required and are clearly displayed. Measurement data can easily be integrated in the existing control system, as the Nivobob also offers, alongside the 0/4-20mA signal output, both Modbus and Profibus DP communication.
The wide range of supply voltages, a multitude of different process connections and accreditations, that are also applicable to the North American market ensure that Nivobob is suitable for the international market.
To ensure reliable measurement results in all applications, there is a choice of sensor weights in differing material and shapes. Apart from measurement in typical applications, such as powder or other fine and coarse material, it is also possible to measure the level of interfaces and liquids.

So that the customer gets the best equipment solution according to his requirements, we recommend this simple
procedure using the following pages:
• Define the dimension of the fitting or interface (e.g. thread G2“, DIN-flange DN25/PN16, etc.)
• Determine the electrical connection (e.g. terminal box, cable entry, plug, etc.)
• Find out the operating conditions, min. and max. operating pressure, temperature and specific gravity of
the media at the max. operating temperature.
• With the size of the fitting and material of the instrument, a guide specification can be selected on pages
105 to 107.
• The full and final specification can now be generated by reference to the „type key“ on pages 108 to 109.
• With the type description and the technical operating conditions a price quotation can be made or the
instrument can be ordered.
• Specification of the requested approval.

Continuous level measurement over a measuring range of up to 8 meters
The Tower-Sens is a rod detector based on the well-known level gauging system LB 490 Uni-Probe. It has been designed specifically to monitor large measuring ranges.
With only one electronic unit and only one flameproof-housing, the Tower-Sens is significantly more economical than systems comprising several short, cascading detectors. Moreover, the wiring efforts and the risk of complete system failure are drastically reduced.
The combination of good value, reliability, accuracy and low source activity make the Tower-Sens the ideal solution for measuri

Magnetic floats
Magnetic floats are used to detect dynamic fluid levels, either as single floats in homogeneous media or as interface level detectors in fluids with different densities.
Magnetic floats have a magnet inside and are placed on a guiding rod. For interface level detection, several floats can be placed on one single guiding rod.
The magnetic float actuates the detection circuit either by means of a reed contact or - for a more accurate reading - a magnetostrictive sensor.
We produce both magnetic switches for reed contacts and magnetic floats for magnetostrictive sensors
|
|
Magnetostrictive fluid level measurement
To measure liquid levels using magnetic floats, an electronic detection device is necessary.
There are two common detection methods that use either reed contacts or magnetostrictive devices. When reed contacts are used, these are located within the guiding rod. Magnetostrictive devices, on the other hand, use variations in the magnetic field to detect the position of the float, which gives far more accurate readings than a reed contact.
