The KATflow 150 is for permanent flow metering applications. Its modularity offers comprehensive configuration options to make the instrument suitable for everything from simple water flow measurements to energy flow monitoring, automated process control and product recognition.

General information

The transmitter electronics are housed in a corrosion-resistant, wall mounted enclosure and can be powered by AC or DC power supplies. By offering a wide range of input, output and communication inferfaces such as RS 485, Modbus and HART*, the flow meter can easily be connected to process automation systems.

katflow150-coverThe KATflow 150 of U-F-M can be supplied with one or two measurement channels. It is therefore ablte to offer a cost-effective solution for multi-pipe metering applications. The dual-channel measurement function can also be used to monitor one single pipe in a two-path sensor mounting configuration in order to increase the accuracy under difficult flow conditions with disturbed flow profiles. The incorporated calculation functions Sum, Difference, Average and Highest Value complete the dual-channel feature.

As with all other U-F-M / Katronic models, the KATflow 150 offers an intuitive instrument menu and Setup Wizard which guides the user step-by-step through the meter configuration.

The correct installation of the clamp-on sensors on the pipe is made easy by the incorporated Audible Sensor Positioning Assistant™ which gives the user visual and audible indications during sensor mounting.

Heat quantity measurement and process outputs

The KATflow 150 of U-F-M B.V. offers a heat quantity measurement function that turns the instrument into a energy meter. When equipped with this feature, the KATflow 150 incorporates measured flow and temperature values delivered by two PT100 sensors into heat flow and heat quantity.
Apart from the heat quantity measurement function the flow meter can be equipped with a selction of process outputs. The customer can choose from a list of outputs including 0/4 to 20 mA, Open-Collector (pulse), relay, voltage and frequency.

Data logger and download interface

The KATflow 150 of U-F-M B.V. / Ultrasonic Flow Management can be ordered with an internal data logger, which is available in two sizes to store up to 30,000 or 100,000 measurements with each measurement comprising up to 10 units (velocity, volume, mass, heat flow, heat quantity and temperature units) which can be selected by the user before each measurement.

In combination with a data logger, the KATflow 150 is supplied with the KATdata+ software which enables the user to download and visualise the flow data on a computer after the measurement or in real-time using the embedded terminal function. The data can be transferred via RS 232 or USB.

Additionally, the KATflow 150 of U-F-M B.V. can be used for pressure, temperature and viscosity compensated flow measurement systems.

The specification of the instrument can be taken one step further by applying the optional speed-of-sound measurement function. This enables the KATflow 150 to be employed for contactless concentration monitoring applications (e.g. as product recognition system).

Ex approved transmitter enclosure and ultrasonic sensor options

In addition to the KATflow 150 standard version for safe area applications, Katronic also offers Ex certified ultrasonic transmitter and sensor modifications for permanent installation in hazardous areas.

The flow sensors supplied with the KATflow 150 are manufactured with a stainless steel head and sturdy cable conduit ensuring extreme robustness and are fully auto detected.

The ultrasonic sensors cover a pipe diameter range from 10 mm to over 3,000 mm and process temperatures from -30 °C to +200 °C.

Measurement technology

All KATflow clamp-on ultrasonic flow meters of U-F-M B.V. / Ultrasonic Flow Management apply ultrasonic transit-time measurement technology.

This enables the instruments to provide highly accurate and reliable flow data for almost any kind of liquid regardless of its electric conductivity.
