Product Overview
The Series IS/PX/TX In-Line Flowmeter provides a highly visible, variable-area solution built for both liquids and gases across a wide range of applications. With a transparent flow tube and printed scale, it enables direct visual monitoring of flow without the need for external sensors or indicators. Optional field-adjustable reed switches support high or low flow alarm functionality.
Constructed with a variety of materials - from PVC tubes to polysulfone with 316 SS fittings - and multiple fitting options (brass, aluminum, PVDF), this meter adapts to diverse fluid media including process water, compressed air, ultra-pure water, nitrogen and chemical streams. It supports flow sizes from 3 GPM up to 14 000 SLPM air, enabling broad use-case coverage.
Designed for practicality in installation and service, the flowmeter mounts via standard NPT threads (½″, ¾″, 1″, or 1½″) and can be oriented in any installation angle without affecting functionality. With a very low pressure drop (~4 psi at full flow) and optional alarm switch kits (single or dual piston switch configurations), it’s suited to OEM, water-treatment, HVAC, industrial and process environments.
For applications requiring visual flow verification, flexible mounting, material versatility, and optional alarm functionality, the Series IS/PX/TX In-Line Flowmeter offers a dependable and cost-effective solution.
