Detailed Flow Switch Description
The operating principle bases on a free - floating magnetic piston, which
responds only to the motion of fluid within the pipeline, not to static
or system pressure.
Features and specifications:
a) Housing material: brass
b) Piston material: PVC or PBT
c) Spring material: stainless steel SUS304
d) Retaining rings material: stainless steel SUS304
e) Operating pressure: 300 PSI max. In the presence of fluid flow, controlled movement
of the piston actuates an external hermetically sealed reed switch, thus
producing the required signal which can be used to actuate audible or
visual alarms as well as relays or other.
f) Temperature range: -40 - 125oC
g) Reed switch carry current: 1.5A
h) Reed switch current: 1.0A max.
i) Reed switch voltage: 300V AC, 250V DC
j) Reed switch power rating: 70A
k) Lead wire: AWG 22, 300mm length, to 18, UL1430, free lead wire
l) Flow range: 0.75L~1.0L min.
m) Set point accuracy: ±10% max.
n) Set point difference: 15%
o) Repeatability: ±2% max.
p) Mounting orientation (horizontal or ): as signal of flow
direction
q) Mounting thread: FNPT.3 / 4", FNPT.1"
r) Adequate filtration and sealing
s) Procedures should be used when mounting in flow line
t) The flow set point is adjustable, made in our company
