Original Press Release:
New Viscosity Compensated Flow Meter/Switch Designed for Oils and Other Viscous Fluids
Hudson, MA-Clark is pleased to introduce their new DS08 Flow Meter/Switch. Specifically designed to monitor and measure the flow of viscous fluids like lubricating oils, hydraulic fluids, transformer oils, and other fluids with viscosities up to 600 cSt, DS08 Flow Meter/Switches feature small mounting dimensions, brass or stainless steel connections, high switching accuracy, and universal mounting position.
Rated for flow rates of 30-90 l/min, DS08 Flow Meter/Switches work according to a modified variable area principle where a float is guided in a cylindrical measuring tube by means of a spring. The flowing medium moves the float in the flow direction. An externally mounted pointer indicator magnetically coupled to the float follows the float position, indicating the flow rate on a scale. DS08 Flow Meter/Switch also incorporate a reed contact mounted outside the meter in a sealed housing. When the float reaches the position of the reed contact the switch will close. With higher flows the float moves further upward until it reached a built-in float stop keeping the switch closed and ensuring a bistable switch function at any time.
