## Details

This unit has a straight junction.

## Overview

Thermal dispersion insertion flow meter designed for measuring gas flow velocity and volumetric flow rate in pipes, ducts, and stacks. Features dual RTD sensor configuration with one heated sensor and one reference sensor to detect mass flow based on thermal cooling effect. Operates in high temperature environments up to 850°F with 12-inch insertion length for large diameter applications. Provides 4-20mA analog output with digital communication capabilities. Installs through threaded or flanged fittings with hot-tap capability for live installation. Commonly used in combustion air monitoring, flare gas measurement, biogas applications, and industrial process gas flow monitoring in power plants, refineries, and manufacturing facilities.

## Function

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.

## Platform

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.

## Application

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.

## Accessories

Power supply options include 85-264 VAC 50/60 Hz (max 24 W) or 24 VDC ±10% (max 1 A); integral or remote user interface with backlit 2-line, 16-character display/keypad; optically isolated 4-20 mA output(s) with up to two solid-state relays; solenoid valves and purge air tanks available for automated purge cycle; sensor options include Alloy C-276 or abrasion-resistant chromium nitride coating and PTFE compound chemical-resistant coating; mentioned connectors/interfaces include electrical power connector and sensor wiring harness, typically multi-conductor suitable for power, signal, and communication; interface protocols include RS-232 and HART communication; mechanical mounting is insertion style with process pressure rating up to 300 PSIG and process temperature rating -40°C to 260°C (HT) or up to 500°C (HHT) options available.

## Interface

Integral user interface with backlit LCD display and keypad, rotatable in 90° increments; input power via AC (85-264 V, 50/60 Hz) or DC (24 V ±10%); two optically isolated 4-20 mA analog outputs with ±48 VDC isolation, 12-bit resolution, maximum loop resistance 300-1400 O depending on supply voltage; RS-232 serial communication; digital relay alarms; built-in configurable flow display supporting multiple engineering units; sensor insertion probe for process connection; rugged welded thermal RTD sensors for velocity and temperature measurement; optional remote electronics enclosure with aluminum housing; standard process connection hardware included.
