ADF-23 Adjustable Flow Calibrator

In production sites or laboratories, leak detection systems need regular accuracy verification, but large calibration equipment is often bulky, expensive, and difficult to move. The ADF-23 Adjustable Flow Calibrator is a portable, accurate, and easy‑to‑use flow calibration tool that simulates small leak flows, helping you quickly inspect, calibrate, and verify leak testing systems. The ADF‑23 uses digital flow meter technology, allowing precise setting of the desired flow rate (cc/min) via a high‑precision flow control valve and real‑time display, independent of ambient pressure/temperature changes. It is lightweight (only 570 g), fits into a standard tool case, and performs on‑site calibration anytime, anywhere – making it an indispensable verification tool for ISO 9001 and other quality management systems.

Technical Advantage

Key Advantages

Portable & Easy to use: Handheld design, built‑in 9V battery provides approx. 60 hours of continuous operation – no external power needed. Suitable for workshops, field use, laboratories, etc.
High accuracy: Measurement accuracy ±1.0% of set point (S.P.), better than most industrial field requirements.
Multiple ranges: Three flow ranges available, covering simulation from very small to larger leaks.
Environmentally independent: Built‑in temperature and pressure compensation algorithms ensure stable and reliable readings under different conditions.
Plug & play: Includes standard measurement hose and storage case – ready to use out of the box.

Main Applications

Leak testing instrument verification: Periodically verify whether the accuracy of air tightness testers remains within allowable limits.
In‑house periodic calibration: Perform periodic flow calibration of testing equipment on production lines according to ISO 9000 requirements.
Leak simulation: Artificially set a specific leak rate to verify that the test system alarms correctly.
Troubleshooting leak test systems: When a system behaves abnormally, use the calibrator to determine whether the issue lies with the instrument or the tooling/piping.
Special environment measurement: When no standard leak is available on‑site or large equipment cannot be used, the portable calibrator performs quick temporary measurements.

How to Use

Connect the calibrator outlet to the system under test (or via a tee into the test loop).
Turn on the power, adjust the flow control valve to the desired flow rate (read on the real‑time display).
Start the leak tester and compare its measured value with the calibrator set point to determine deviation.

Accessories Included

Rugged storage case (395×295×106 mm)
Operation manual and factory calibration certificate
Measurement hose (Φ3 mm, approx. 1000 mm length)
Needle valve, soft sleeve, protective cap, etc.
Optional: USB/RS232 data output cable (for printing or data logging)

Maintenance & Warranty
