Here is an informative article about the **100 L/h flow meter**, written in English. --- ### The 100 L/h Flow Meter: Precision in Low-Flow Measurement In the vast world of fluid dynamics and industrial process control, flow meters are the silent guardians of accuracy. While many imagine massive pipes carrying thousands of liters per minute in oil refineries or water treatment plants, a significant portion of industry relies on the precise measurement of much smaller volumes. The **100 L/h (liters per hour) flow meter** is a prime example of this specialized technology, serving as a critical instrument in applications where every drop counts, from laboratory experiments to delicate chemical dosing. #### Understanding the Scale To put 100 L/h into perspective, this flow rate equals approximately 1.67 liters per minute or about 28 milliliters per second. This is a low to medium flow rate, often found in small-scale industrial processes. It is not the flow of a garden hose, but rather the steady, controlled movement of a liquid through a narrow channel. At this scale, the design of the flow meter must be sensitive enough to detect small changes in flow while remaining robust enough to withstand continuous operation. #### Common Operating Principles A 100 L/h flow meter is not a single device but a category of instruments that utilize different physical principles to measure flow. The most common types for this range include: 1. **Thermal Mass Flow Meters:** These are arguably the most popular for low-flow gas and liquid applications. They operate by measuring the heat dissipated by a heated sensor as fluid flows past it. The rate of heat loss is directly proportional to the mass flow rate. For a 100 L/h stream, a th 100 L/h flow meter

It consists of a tapered glass or plastic tube containing a float (a "rotor"). As fluid flows upward through the tube, it lifts the float. The height of the float is proportional to the flow rate. For a 100 L/h range, a rotameter is a reliable visual indicator, though it requires manual reading and is best for steady flows. 3. **Oval Gear Flow Meters:** These are positive displacement meters designed for high accuracy with viscous liquids. They contain two rotating oval gears that trap fixed volumes of liquid. By counting the gear rotations, the meter precisely determines the total volume passed. A 100 L/h oval gear meter is excellent for applications like fuel metering or hydraulic oil monitoring, where even small inaccuracies are costly. 4. **Coriolis Mass Flow Meters:** While often associated with larger flows, modern Coriolis meters are available in miniature versions capable of measuring 100 L/h with exceptional precision. They measure mass flow directly by detecting the vibration of a U-shaped tube. These are the gold standard for accuracy but are significantly more expensive. #### Key Applications The 100 L/h flow meter finds its home in industries where precision and control are paramount: - **Pharmaceutical Production:** In drug manufacturing, ingredients must be mixed in exact proportions. A 100 L/h meter ensures the precise addition of active pharmaceutical ingredients (APIs) or solvents. - **Chemical Dosing:** Water treatment plants and industrial boilers use this meter to inject precise
