IN-FLOW Industrial Mass Flow Meters/Controllers for Gases

Product catalog summary

Introduction
Bronkhorst High-Tech B.V. is a prominent European manufacturer specializing in low flow thermal and Coriolis Mass Flow Meters/Controllers. Their products are customized for various environments, including laboratories and hazardous areas.

IN-FLOW Series Overview
The IN-FLOW series is engineered for industrial settings, featuring a robust design (IP65) suitable for pilot and production plants, including hazardous areas with optional ATEX, FM, or KCs approvals. These meters provide a wide range of flow rates and pressure ratings, equipped with digital pc-boards for high accuracy and rapid response.

Selectable Gases and Flow Ranges
The series offers Multi-Gas/Multi-Range functionality, allowing on-site rescaling of instruments for enhanced flexibility and efficiency. The 'FlowTune' software facilitates easy configuration changes.

Mass Flow Controllers
Controllers can feature integrated or separate control valves, providing fast and smooth control. Various valve types are available for different applications, including high flow rates and low differential pressure scenarios.

General Features
Key features include weatherproof housing, fast response, high repeatability, and RoHS compliance. Digital features support various fieldbus interfaces and user-configurable control characteristics.

Technical Specifications
Specifications include accuracy, repeatability, operating temperature, pressure sensitivity, and more. Mechanical parts are made from stainless steel, with various seal options. Electrical properties cover power supply requirements and communication options.

Models and Flow Ranges
The document lists various models with their respective minimum and maximum flow ranges, suitable for different pressure ratings.

Multi Gas/Multi Range Features
This functionality offers rangeability up to 187.5:1, user-programmable ranges, and high accuracy. It is optional for low-flow series and requires digital communication for extended rangeability.

Thermal Mass Flow Measuring Principle
The sensor uses a stainless steel capillary tube with resistance thermometers. The temperature difference measured is proportional to the mass flow, with a patented laminar flow element ensuring accurate flow-split.

Fields of Application
The IN-FLOW series is used in various industrial applications, including process gas measurement, burner control, and gas consumption measurement.

LOW-ΔP-FLOW Series Introduction
Bronkhorst has developed the LOW-ΔP-FLOW series mass flow meters and controllers for applications with minimal differential pressure. These instruments feature minimized flow resistance and reduced clogging risk, suitable for up to 50 ln/min air-equivalent flow control applications.

Specifications
The LOW-ΔP-FLOW series includes mass flow meters and controllers with various models and dimensions. The models are designed for different flow rates and pressure ratings, with options for high flow and wafer type configurations. The pressure ratings range from 64 bar to 700 bar, and the flow ranges vary depending on the model and pressure rating.

Control Valves
For higher flow rates at low differential pressures, special control valves with pressure compensation bellows (series F-004) are used. These valves are integrated with the flow meter's electronic PI-control function.

Communication and Output
The instruments support various communication protocols, including RS232, POWERLINK, DeviceNet™, EtherNet/IP, CANopen®, Modbus, PROFIBUS DP, FLOW-BUS, EtherCAT®, and PROFINET. Analog output options include 0-5 Vdc, 0-10 Vdc, 0-20 mA, and 4-20 mA.

Connections and Mounting
Connection types include compression and face seal options, with mounting available between flanges of different standards (DIN and ANSI). Internal seals are available in Viton®, EPDM, and Kalrez® (FFKM).

Company Information

IN-FLOW Industrial Mass Flow Meters/Controllers for Gases-5

The heart of the thermal mass flow meter/controller is the sensor, that consists of a stainless steel capillary tube with resistance thermometer elements. A part of the gas flows through this bypass sensor, and is warmed up by heating elements. Consequently the measured temperatures T1 and T2 drift apart. The temperature difference is directly proportional to mass flow through the sensor. In the main channel Bronkhorst applies a patented laminar flow element consisting of a stack of stainless steel discs with precision-etched flow channels. Thanks to the perfect flow-split the sensor output is...
