Variable-area flowmeter DS11

for waterfor gas

The flowmeters DS11 operate according to the proven vari­able area principle. The flowing media moves a float upwards against gravity in a conical measuring tube. The height of the float indicates the flow rate and may be read off a burnt-in scale on the measuring tube. Optional inductive contacts, which are mounted on the meas­uring tube, may be used for flow rate limit detection. All meters are equipped with an integrated needle valve for exactly regulating the flow rate. Typical applications Variable area flowmeters model DS10 are mainly used for measuring and monitoring the flow rate of low- viscous liquid and gaseous media. Scales for water or air at standard operating conditions have already been defined. For other media or different process conditions special scales are available. fittings of PVDF with integrated needle valve with up to 2 swith contacts
