AccuThermModel FLT-M1 -Flow Sensor for Liquid and Gas Mass Flow Measurement

SHARE

The FLT-M1 flow sensor is engineered to measure the mass flow of liquids and gases using a mini Coriolis system with an S-shaped measuring tube and temperature sensor. This sensor is directly installed into flow pipes via a manufacturer-specific connection, where it leverages Coriolis forces to determine flow rates. It transmits measured values such as mass flow, density, and temperature to a higher-level system via Modbus TTL. Capable of managing pressure lines up to 100 bar at a rate of 200 measurements per second, the device captures flow changes within a step response time of 50 ms. Designed for OEM applications, particularly in plant and machine construction, it is optimized for high-volume, low-variance measurements. The sensor is not standalone and requires device integration. Available in two variants, FLT-M1_i1 and FLT-M1_i2, it caters to differing flow ranges and requirements, providing essential data for precise dosing and mixing operations. The sensor operates within a temperature range of -10°C to +70°C and adheres to IP protection standards when installed. It lacks intrinsic safety features but complies with relevant environmental and electromagnetic compatibility standards.

The FLT-M1 flow sensor employs Coriolis technology to measure mass flow in liquids and gases, fitting directly into flow pipes. It offers real-time data via Modbus TTL, making it suitable for precision-focused OEM applications in plant and machine construction.

DESCRIPTION

The FLT-M1 flow sensor has been designed to determine the mass flow of liquids and gases. This is done with a mini Coriolis measuring system with an S-shaped measuring tube and a temperature sensor. 

The flow sensor is installed directly in a flow pipe via a manufacturer-specific connection. If medium flows through the flow sensor, the measured value information is generated with the aid of Coriolis forces. The measured values are fed to the higher-level system via a Modbus TTL. 

It is possible to take flow measurements for pressure lines up to 100 bar at a measuring rate of 200 Hz (200 measured values per second). Flow changes are recorded with a step response time of 50 ms. 

Target audience
