Flow switch pressure-rated to 2,000 psi

PKP Process Instruments’ DS04 flow switch measures and monitors the flow of low viscosity liquids and gases. Applications include monitoring equipment cooling loops used on laser systems and plasma welding systems, as well as pump monitoring/control and alarm functions for process flow.

PKP Process Instruments’ DS04 flow switch measures and monitors the flow of low viscosity liquids and gases. Applications include monitoring equipment cooling loops used on laser systems and plasma welding systems, as well as pump monitoring/control and alarm functions for process flow. DS04 works on a variable-area principal and uses a float guided in a cylindrical measuring tube by means of a slotted nozzle; the flowing medium moves the float in the flow direction. One or two reed switches in a sealed housing are magnetically coupled to the float and factory preset or field adjustable over the range of the instrument. An optional external pointer indicator magnetically coupled to the float can be supplied to indicate flow rate. DS04 is supplied with brass or 316-stainless steel wetted parts and Buna or Viton seals. The pressure rating is 2,900 psig for brass, 4,350 psig for stainless. www.pkp.eu PKP Process Instruments, Inc.
