EX250S-sensor

Product Description

It features a rugged, corrosion-resistant PVC body and a 316 stainless steel paddlewheel, ensuring durability in demanding industrial environments. The sensor operates on the Hall-effect principle, generating a frequency output proportional to flow velocity, which can be interfaced with SeaMetrics' digital displays, batch controllers, or PLCs. With a flow range of 0.3 to 8 meters per second (1 to 26 feet per second), the EX250S is suitable for pipe sizes from 2 inches and above when installed in a full-pipe tee. The sensor's insertion design allows for easy installation and removal without draining the pipeline, reducing downtime during maintenance. It is compatible with a variety of liquids, including water, wastewater, and many chemical solutions, provided they are compatible with PVC and 316SS wetted materials. The EX250S is part of SeaMetrics' EX series, known for its reliability and ease of integration. It comes with a 25-foot cable as standard, with options for longer lengths. The sensor is powered by 5-24 VDC and provides a square-wave pulse output, making it ideal for use with SeaMetrics' SPX series transmitters, BAT series batch controllers, or any compatible flow monitor. Its compact design and robust construction make it a preferred choice for OEMs and end-users in water treatment, irrigation, and industrial process control. The SeaMetrics EX250S is a paddlewheel flow sensor designed for insertion into a 2-inch PVC tee, providing accurate flow measurement for a wide range of conductive and non-conductive liquids.

Technical Specifications

Version & Model Difference

The EX250S is part of the EX series. Variations include the EX250P (with PVDF body for higher chemical compatibility) and EX250H (with Hastelloy paddlewheel for aggressive media). The EX250S uses a 316SS paddlewheel, which is suitable for most water-based applications. For non-conductive liquids, the EX series uses a different sensing mechanism (e.g., RF or ultrasonic), but the EX250S is specifically for conductive liquids. The 'S' suffix indicates the standard stainless steel paddlewheel option.
