Model K09 Heinrich-Low Volume

Flow measuring of liquids and gas can be used in the chemical industry or medical or laboratory engineering. The remarkable features of this device are Precision, reliability, and efficiency. This device has a robust mechanical system with a low rate of wear and extremely compact design. The K09 meter is suitable for flow measurement of liquid or gaseous products in pipes. It shows the current flow rate in volume or mass per unit in time


Flow metering of liquid or gaseous products in pipelines. The current flow rate in volume or mass per unit in time is displayed.
