The flowmeter DS12 operates according to the proven variable area principle. They devices must be mounted vertically with flow direction from bottom to top.
They consist of a tapered glass measuring tube with a free rotating float. Because of the special design the devices have a very low pressure drop a high measuring accuracy. The glass measuring tube allows a direct display of the flow rate and a visual monitoring of the medium. Because of its length of 300 mm it offers a high resolution.
The measured value can be read at the upper edge of the float. Therefore is a scale burned in the measuring tube. Optionally the flowmeter can be equipped with an adjustable limit switch.
Typical applications
Because of the wide choice of measuring ranges the flowmeter DS12 can be used in the entire industry. for measuring of low flow rates, water from 0.002...0.025 l/h, air from 0.1...1.75 Nl/h, as well as high flow rates, water until 1...10 m³/h, air until 15...160 Nm³/h. The devices are particulary appropriate for a high accuracy, class 1,6, with high resolution or they can indicate low inlet pressures (eg. test rig).
A variety of connections allows universal application. As standard there are BSP and NPT threads available. Optionally the devices can be equipped with a bonded socket, hose fitting in various materials depending on the application.
