Katronic Fixed installed and portable clamp-on heat meters

How it works
A set of ultrasonic flow sensors is installed on a suitable pipe section along with two PT100 temperature sensors which are mounted to the pipe at the inlet and outlet of the chosen location. From the specific heat capacity of the flowing medium, the energy transmission can be determined using the calculated mass flow
rate and temperature difference between the inlet and outlet.

General information
The ultrasonic  flow sensors cover a pipe diameter range from 10 mm to over 3,000 mm (0.4 to 118 inch) and work on any common pipe material and temperatures from -30 °C to +200 °C. The PT100 clamp-on temperature sensors supplied with the flow meter match this temperature range and can be easily connected to the flow meter.

Parameters of the measurable liquids are stored on the transmitter and can be chosen from a menu. This includes commonly used heating media such as hot water and oil, as well as refrigerants such as chilled water, water/glycol mixes and R-coded chemical refrigerants.
The KATflow 230 and KATflow 150 feature an internal data logger with a capacity of up to 100,000 samples, which stores all measured and totalized values and parameter sets. When equipped with a data logger, the flow meters are supplied with the KATdata+ software which enables the user to download and view the flow data on a computer. The data can be transferred via the instrument’s RS 232 interface for which an RS 232 to USB converter cable can be supplied.

Both the KATflow 230 and KATflow 150 offer process outputs including 0/4…20 mA current outputs, open-collector outputs with totalizer pulse, and digital relay outputs. Additionally, the KATflow 150 can be equipped with an RS 485 interface. Apart from the units specific to the heat quantity measurement function, the Katronic flow meters display various units for the volumetric flow rate, flow velocity, mass flow rate, flow volume and mass.
The measurement units specific to the heat quantity measurement function displayed by the KATflow 150 and KATflow 230 are W, kW, MW for heat flow, and J, kJ, MJ for heat quantity.
