Presentation and Use:

The LF Technologies flow meter calibration bench is used to calibrate, verify or adjust flow meters with full traceability. Ideal for industrial maintenance and quality control. This bench ensures performance control, compliance with standards and contributes to reducing operating costs.

Operating principles

The flow meter to be calibrated is connected to a hydraulic (or pneumatic) test line.
The test fluid (often water) is circulated via a servo pump.
A pilot-operated control valve adjusts the flow rate to achieve the desired test levels.
A master flow meter (reference standard) is placed in series to compare measurements.
The system performs flow rate steps to cover the entire measurement range of the sensor being tested.
The embedded software controls the sequences, records the data, calculates the deviations/uncertainties, and generates a calibration report.
Compensation systems (temperature, pressure) can be added to ensure accuracy.

OPTIONS

Thermal enclosure

Directly integrated into the test bench, the thermal chambers are capable of simulating extreme environments (from -180°C to +600°C) and are reproducible. The temperature is regulated and controlled during the test according to pre-set parameters (ramps and steps). Thermal chambers are ideal for carrying out long-term tests or for preparing a sample prior to testing. The independent chamber is heated using a gas or liquid bath, with a temperature gauge positioned as close as possible to the sample under test. Robotic rapid transfer systems minimise variations in product temperature between the climatic chamber and the test area.nvironments (from -180°C to +600°C) and reproducible.
