KATRONIC Portable clamp-on ultrasonic flow meter

 Katronic Portable clamp-on ultrasonic flow meter

General information

---

In contrast to its hand-held couterpart, the KATflow 230 offers two measurement channels which enable the instrument to monitor two pipes simultaneously. This 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 Katronic models, the KATflow 230 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 230 offers a heat quantity  measurement  function that turns the instrument into a portable energy meter. When equipped with this feature, the KATflow 230 incorporates measured flow and temperature values delivered by two PT100 sensors into heat flow and heat quantity – this is valuable information to assess the efficiency of heat exchangers and HVAC systems.
Apart from the heat quantity measurement function the flow meter can be equipped with a selction of process outputs. The customer can choose between 0/4 to 20 mA, Open-Collector (pulse) and relay outputs.

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.
