Siemens PLC Interface Module with 0.7 mm Resolution Digital Input and 500mA Overcurrent Protection

Product Overview and Core Specifications​

The +GF+ model 727790211 is a Signet 2532 Insertion Paddlewheel Flow Sensor, engineered for reliable and cost-effective flow monitoring in a wide range of industrial water and process liquid applications. This sensor operates on a mechanical principle, where the fluid's flow spins a paddlewheel, generating a frequency signal directly proportional to the flow rate. Constructed for durability, it features a PVDF body and a Polysulfone paddlewheel, offering excellent resistance to a broad spectrum of chemicals. Key performance parameters include a flow velocity range of 0.3 to 10 m/s, an operating temperature maximum of 80°C, and a pressure rating of 150 PSI. It provides a standard 2-wire, 4-20 mA analog output or a pulse output for totalization, ensuring seamless compatibility with most PLCs and process controllers. Its insertion design allows for easy installation into pressurized pipes via a hot-tap fitting.

​Functional Application and System Integration​

The primary purpose of this sensor is to provide continuous flow rate measurement and totalization (flow summing) for process verification, control, and alarm functions. Its core functionality is vital in applications requiring reliable flow confirmation, such as controlling pump sequences, ensuring adequate cooling flow, monitoring filter backwash cycles, and verifying flow in chemical dosing lines. It is extensively used in water treatment, HVAC systems, industrial cooling, and light chemical processing. The sensor is designed to interface directly with +GF+ Signet 9900 transmitters or any other receiver capable of accepting a 4-20 mA or pulse signal. This integration allows it to be a fundamental component in automated systems, helping to prevent pump run-dry conditions, optimize process efficiency, and provide crucial data for system management and maintenance scheduling.

​Distinctive Advantages and Operational Value​

The key advantage of the +GF+ 727790211 lies in its exceptional value proposition, combining low initial cost with simple installation and reliable performance. Its straightforward mechanical design translates to a robust and maintenance-friendly solution. The insertion style installation minimizes pressure loss and allows for service or removal without shutting down the entire process line, drastically reducing downtime. Users benefit from its versatility, as it is suitable for a wide array of non-abrasive liquids and pipe sizes. Compared to more complex flow meters, it offers a highly economical solution for applications where extreme high precision is not the primary concern, but dependable and stable flow indication is critical. This makes it an ideal choice for OEMs and end-users seeking to maximize reliability and minimize total cost of ownership.
