CAT.No.CBD008E-8

Vortex Flow Monitor

Eggs DELTA Pulse● Made of PPS resin: compact, lightweight, and economical.
● Ideal for consumption management of energy-fluids or coolant,

as well as end-of-process flow monitoring via installation tovarious equipment.
● Capable of measuring wide range of liquid and gas.
● Resistant to dust and mist. Capable of wet-gas measurement.
● Maintenance free due to absence of moving parts.
● ATEX, TIIS compliant.
