Key Features

• Variable Area Principle: Operates without an external power supply for simple and reliable flow measurement.
• High Pressure and Temperature: Rated for a maximum pressure of 16 bar and a maximum temperature of 300°C, ensuring durability.
• High Accuracy: Provides precise flow rate readings in a variety of industrial gases and liquids.
• Wide Flow Rate Range: The scale shows a flow rate range of 1.5 to 15.0 Nm³/h for gas flow at standard conditions.
• Robust Design: The `RR` in the model number indicates a robust and durable design for demanding environments.

Measuring Principle

The H250 is a robust flowmeter that operates on a simple principle: a float inside a tapered tube rises with increasing flow, and its position on the scale corresponds to the flow rate. The `M9` in the model number refers to the specific indicator type. The meter is calibrated for air with a density of 1.293 kg/Nm³ and a viscosity of 0.0181 mPa·s at 20°C and 6 barg.
