Liquid flow Helical Rotor sensor and meter

Listing ID #4911014

BROIL Developed and Produced helical rotor flow sensor specially for Liquid dispensing industries, 
now a day liquid dispensing industries use plastic turbine flow sensor its k factor change with flow rate so 
for solution we developer helical rotor plastic flow sensor with same pulse k factor for full range also provide 
very good accuracy and repeatability in full range of measurement With very low pressure loss.

Plastic Helical flow meters are positive displacement meters with a very favorable low pressure drop behavior. therefore perfectly suited for the flow measurement of very high to low viscosity fluids.  Due to wide measuring ranges, high accuracy and resolution helical flow meters are an excellent  choice for laminating systems, painting systems, adhesive dispense systems,  as well as batching systems for various fluids.
Tchnical specification of plastic helical rotor flow sensor and meter

Material of construction:

Enclosure                   : PA66 + GF

Rotor                          : PA66/POM/PPS

Shaft                           : Hard Stainless Steel-316

bearing : carbon/pom with hard S.S. BALL

1) Pulse output sensor :

a) Hall sensor

Power voltage: 5 to 24  V DC/ Low power: 2 to 5 V DC

Output signal: NPN open connector                                          

Output:  

high electric level : High than 4.5 VDC( input voltage 5 VDC)

low electric level  : lower than 0.5 VDC( input voltage 5 VDC)

b) Reed sensor

c) pick up coil - two wire/ amplified three wire option

 2) Battery operated meter  :

Power voltage: 3.0 Vbatteries can be used more than 1 years in a row.

display mode:

Double row Liquid Crystal Display (LCD), as follows:

     L XXX. X    four instantaneous flow (m3 / h) or L/h

     L XXXX. X    Partial total  (m3 / h) or L/h

     XXXXX.X*100  eight cumulative flow (m3)  or L

    XXXXX.X*100  eight cumulative flow (m3)  or L( never reset total)

Cumulative flow: automatically expand the display precision, the cumulative flow/partial values can be reset.

Power-fail protection: instrument coefficient, the Total flow values ten years is not lost when power supply drop.

3) Display with 4 to 20 mA Output

Power voltage: 24 V DC

Output signal: 4 TO 20 mA
