Model: K32- with glass tube Heinrichs Low Volume-variable area

 Model K32 Low Volume - variable area - with glass tube

The K32 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 measuring of liquids and gas can be used in the chemical industry or medical or laboratory engineering.

Precision, reliability, and efficiency are the remarkable features of this device. This device is a robust mechanical system with a low-rate of wear.

The variable-area flowmeter consists of a stainless steel device with an integrated conical measuring tube made of glass and a vertically
movable float. The valve for setting the flow rate is built-in


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