PLC Interface Module with 4 Changeover Contacts IP66/IP67 Protection and 250V AC Maximum Rating

​Product Overview and Core Specifications​

The +GF+ model 727690423 is a Signet 8900 Rotameter, a highly reliable and cost-effective mechanical flow meter designed for visual flow monitoring in a vast array of industrial applications. This variable area flowmeter operates on a simple yet robust principle: the position of a free-floating float within a tapered glass or plastic tube indicates the flow rate, which is read against a integrated scale. Key parameters defining its performance include a variety of body and float material options such as PP, PVDF, and 316SS, ensuring excellent chemical compatibility. It offers a standard operating temperature of up to 100°C and a pressure rating of 150 PSI, making it suitable for many process lines. Available in multiple connection types and sizes, it provides direct, no-power-required flow indication, making it an indispensable tool for quick visual checks and process verification.

​Functional Application and Primary Purpose​

The primary function of this rotameter is to provide continuous, on-the-spot visual verification of fluid flow rates within a pipe. Its core purpose is to enable operators to instantly confirm that a process, such as chemical dosing, cooling water circulation, or filter feed, is operating within expected parameters without the need for complex electronics. It is extensively used in water and wastewater treatment for monitoring filter backwash flow, in chemical processing for observing reagent feed rates, and in industrial manufacturing for ensuring adequate coolant flow to equipment. The simple design allows for easy installation in bypass lines or directly into the main process, offering a straightforward solution for flow visualization that helps in maintaining process stability, preventing pump run-dry situations, and facilitating quick troubleshooting.

​Key Advantages and Operational Benefits​

The significant advantage of the +GF+ 727690423 rotameter lies in its simplicity, durability, and cost-efficiency. It requires no external power, making it intrinsically safe and ideal for use in remote or hazardous locations where electrical devices are impractical. The direct visual reading eliminates potential errors from signal transmission or calibration drift associated with electronic meters, providing immediate and trustworthy data. Its robust construction, often with chemical-resistant materials like PVDF, ensures a long service life even when handling aggressive media. Maintenance is minimal, typically involving only a simple cleaning or float replacement. This combination of zero operational energy costs, high reliability, and low maintenance makes it an exceptionally economical choice for continuous flow monitoring, contributing to reduced downtime and lower total cost of ownership.
