Flow Meters for Gastric Lavage Testers – Simple, Accurate, Reliable
Gastric lavage testers are used in hospitals to check the performance of stomach pumps. These devices measure flow, pressure, and temperature to make sure the equipment works safely.
At the core of each tester is one flow meter. And that is where we come in.
Our oval gear flow meters are made for this job. They measure water flow from 30 to 180 mL/min at pressures below 0.3 kgf/cm². That is almost no pressure at all – a condition where many flow meters fail.
But ours do not.
They deliver repeatability of 1% to 3%, which means the reading is consistent every time. They are also small, so they fit easily into compact testing devices.
Our meters are already number one in China for medical testing applications. We shipped 280 units in 2025 and 50 more in the first half of 2026.
If you need a flow meter that handles low pressure, fits tight spaces, and gives reliable readings, ours are the answer.
Simple. Accurate. Trusted.
