Display - volumetric flow measurement

General description
The METPOINT®️ FLM volumetric flowmeter determines the volumetric flow of compressed air by direct insertion into a pressurized pipe via a standard process connection. Sensors are positioned in-line with the flow to ensure representative measurement. The display version provides local visualization of measured values and an integrated configuration menu.

Measurement principle
Two temperature sensors are arranged sequentially in the flow: the first measures the process temperature, the second is electrically heated and kept at +40 K relative to the first. As mass flow increases, the heated sensor requires more electrical power to maintain the temperature difference. The required heating power is proportional to mass flow; using this value and the pipe inner diameter, METPOINT®️ FLM calculates volumetric flow.

Technology and benefits

• Inline, reliable measurement of volumetric flow for compressed air systems.
• Thermal mass principle: direct conversion of heating power to flow value.
• Quick, simple integration via standard process connection.
• Display version allows local viewing and parameter configuration.
• SF13 variant available with calibrated measuring sections for selected diameters and calibration certificate.
• SF53 pre-calibrated for 53.1 mm tube diameter (universal sensor), adjustable/re-calibrable on request.

Applications
Online end-point monitoring to evaluate compressed air consumption, detect leaks and losses, allocate consumption to production units, support energy management and system sizing.

Features of the display version

• Display and configuration menu for local visualization of values and sensor settings.
• Local selection of units and reference conditions.

Notes on variants

• FLM SF13: supplied with measuring sections for the selected diameter and calibration certificate.
• FLM SF53: pre-calibrated for 53.1 mm; re-calibration to other diameters available on request.

How METPOINT®️ FLM with display works (summary)

• The first sensor measures process temperature.
• The second sensor is heated by +40 K and works against cooling from the flow.
• The electrical power needed to maintain the temperature difference is measured and converted into mass flow and then volumetric flow using the pipe internal diameter.
