PEECO E Series Flow Switch
go here For Hazardous Locations with Maximum Allowable Pressure up to 600 PSI
For Liquid or Gas Service
The go here PEECO E Series Flow Switch is a flow actuated electrical switch and is unique in the field of flow controls. These switches are not a standard shelf item, but are specifically produced to accommodate your application. The PEECO flow switches are maintenance free in lines from 1/16″ to 12′ or larger. The source url PEECO E Series flow switch is explosion proof model. All E Series models are rugged, heavy duty units exceeding all UL Code requirements. Each of the four basic styles are adaptable to many other fittings and configurations. Utilizing 1/4″ thick Heat treated aluminum cover with 5 fully engaged threads, these units are designed to encapsulate any internal explosion. All PEECO explosion proof models meet Class 1, Group D requirements for use in hazardous locations. The housing & cover are both made of heat treated aluminum T-356 and are epoxy coated (for extra protection). Conduit outlet: 1/2″ FNPT on all models; 3/4″ and metric sizing available.

How Does a PEECO E Series Flow Switch Work?
PEECO flow switches are actuated by flow – not pressure. No need to be concerned with minimum and maximum flow … you state your requirements, PEECO will accommodate them. From -450° F to +1500° F. From high vacuum service to 600 psi. Fully field adjustable over the entire range (less than 10% dead band/differential between make and break).
The desired flow indication – increase, decrease, reverse – is transmitted mechanically from the line media by deflection of the paddle through the stem and bellows assembly, causing micro-switch actuation and resultant electrical contact for transmission of signal to whatever ultimate point desired.
Base travel of the PEECO E Series flow switch stem is 1/4″. Standard Micro-switch travel is approximately .005″
Our trained technical staff is available (at no cost to you) for consultation, design suggestions, engineering, layout problems or a general discussion of PEECO flow actuated electrical switches and their place in the dynamics of flow.
