Compact design with no moving parts, ideal for confined spaces.
High chemical resistance due to a seal-free sensor design.
Operates within a process temperature range up to 80°C and pressure up to 10 bar.
Large text display for easy setup and operation.
EHEDG certification and FDA compliance for hygienic applications.
Maintenance-free, reducing operational costs.
Adjustable measuring ranges to minimize variant requirements.

Dimensional Drawings
Detailed dimensional drawings are provided for each nominal width, showing process connections and overall dimensions in millimeters and inches. Key dimensions for NW 10, 15, 20, and 25 are highlighted, emphasizing the importance of maintaining consistent tube diameters before and after the device for accurate measurements.

Mounting Instructions
Proper installation is crucial for accurate volume measurement. Minimum inlet and outlet paths are specified based on the device's nominal width. For high-temperature applications (≥ 60°C), the device should be mounted upside down. Correct and incorrect positioning is illustrated, and operational settings can be adjusted using arrow keys, with options to save settings or exit menus.

Operational Settings
The flow sensors display current flow values in liters per minute, total volume, and a bar graph indicating the percentage of the current measurement range. Users can set parameters for analog output, pulse output, status output, measurement units, creeping flow, and medium calibration. The tube must be fully filled, and the flow direction is specified.

Construction and Specifications
The Flowcont UN is an ultrasonic flow meter designed for non-conductive liquids. It supports various tube sizes with specified minimum and maximum flow rates. Sensor material options include PSU black, and process connectors are available in G1 pipe thread, N1 thread NPT, and C1 Clamp (DIN11864-3). Electronics options include current outputs with different configurations for flow rate monitoring and empty pipe detection.

Catalog excerpts

Flow meter Type: Flowcont UN Ultrasonic flowmeter Flowcont UN Non-contact flow measurement Product description The non-contact, ultrasonic flow sensor Flowcont UN detects the flow volumes of conductive and nonconductive liquids. Swimming against the current requires more strength than with the current – this is the simple fact on which ultrasonic flow measurement according to the phase difference process is based. The device has a compact design, and its wide range of possible applications means it can also be used in restricted spaces. The seal-free sensor design, with high-quality polysulfone (Ultrason S) combined with enclosure rating IP 67, not only makes it possible to use the device in harsh ambient conditions, but also guarantees high process reliability. The large text display also helps ensure simple, fast and problem-free commissioning.
