Katronic KATflow 100 ultrasonic flowmeter

The KATflow 100 is for permanent flow-metering applications. The flowmeter has a reduced specification for applications where the benefits of the KATflow 150 and KATflow 170 are not required. Its small size also allows the installation of the flowmeter in areas where the KATflow 150 would not be practical.

The transmitter electronics are housed in a robust wall- or pipe-mounted aluminium enclosure and can be powered by AC or DC power supplies. The product offers a wide range of input, output and communication interfaces such as RS485, Modbus and the more traditional 4-20 mA and Open Collector pulse.

The meter is flexible, with the software and hardware platform allowing users to configure the flowmeter to suit specific requirements. In its simplest configuration, the unit can be supplied as a blind instrument, with commissioning carried out using a handheld programming tool.

The product 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.

As an optional item, the instrument can be configured for heat-quantity measurement. By using two of the available slots, the meter can accommodate two PT100 temperature sensors. When equipped with this feature, the product incorporates measured flow and temperature values delivered by two PT100 sensors into heat flow and heat quantity.

The flowmeter applies ultrasonic transit-time measurement technology. This enables the instrument to provide accurate flow data for almost any kind of liquid regardless of its electric conductivity.
