The Omni-F Flow Transmitter/Switch is a calorimetric flow sensor designed for measuring flow rates in aqueous fluids. It provides a 4(0)-20mA or 0(2)-10V output, along with a digital display for local indication of flow measurement. The device incorporates two programmable push-pull switches and features a microcontroller for temperature compensation, signal linearisation and amplification. Housed in a stainless steel with a chemically resistant glass display, the Omni-F allows for user configuration of parameters via a removable programming ring and is suitable for industrial applications requiring robust and precise flow monitoring.
The Omni-F Flow Transmitter/Switch is designed to measure flow rates in aqueous fluids using calorimetric sensor technology. This measurement principle allows for the determination of flow speed by monitoring heat transfer, providing a responsive and direct indication of flow dynamics. The device is engineered to output an analogue signal, which can be configured to provide either a 0/4-20mA output or a 0/2-10V output, making it adaptable to various control and monitoring systems.

The Omni-F Flow Transmitter incorporates programmable switching capabilities, offering two independent switch outputs. These switches can be configured to trigger alarms or control external devices based on predefined flow thresholds. The programming interface includes a graphical display and a programming ring, which allows users to set parameters such as switching points and hysteresis. For security, the programming ring can be removed, preventing unauthorized changes to the device’s configuration.
Constructed to withstand industrial demands, the Omni-F features a robust housing made primarily of stainless steel. This material provides excellent resistance to corrosion and mechanical stress. The device also includes a durable glass display, which is designed to be scratch-resistant and chemically resilient, ensuring that the display remains clear and legible over time.
