Heinrich K09-R Low Volume Variable Area with Glass Tube

Wiratama Mitra Abadi 01 22.59 flow measurement,

Heinrich K09-R Low Volume Variable Area with Glass Tube 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.
