Functions

Measures fluid velocity within pipes by inserting a probe directly into the flow stream; compatible with standard conductive and non-conductive liquids in industrial piping systems; integrates via cable to handheld or fixed flow measurement devices; suitable for flow rate monitoring, process control, and fluid diagnostics in chemical, water treatment, and HVAC applications.

Platforms

Designed for high-temperature pipeline applications requiring direct pipe insertion measurement capabilities. Operates in industrial process control systems with 4-20mA analog output signals and digital communication protocols. Interfaces with distributed control systems, SCADA networks, and plant automation platforms through standard industrial communication buses. Compatible with pipe diameters ranging from small bore to large industrial pipelines. Integrates with flow computers, data loggers, and remote monitoring systems for continuous flow measurement in oil and gas, chemical processing, water treatment, and power generation facilities requiring accurate volumetric flow data.

Applications

Provides high-accuracy, high-temperature insertion-type thermal mass flow measurement for industrial gases and air in pipes, ducts, and stacks. Capable of operating in temperatures up to 500°F with optional integrated temperature compensation. Offers direct mass flow measurement without requiring separate pressure or temperature corrections. Commonly used in combustion air monitoring, compressed air systems, natural gas consumption tracking, emissions monitoring, and process gas measurement. Features digital and analog outputs for integration with control systems, SCADA, or DCS networks.
