Helical rotor Positive displacement base DIGITAL WATER FLOW METER developed by "BROILTECH" indiginiously first time in world for water industries, 

Helical rotor Digital Water Meter  design is proven for best accuracy and low pressure loss than turbine and oval gear, so customer got more flow rate and low power consumption, its also not effected on viscosity of liquied and temp. change.

its also use for various liquied flow measurement from low to high viscousity

digital water flow meter technical specification:

Model No : BT- PHTFS-D
Manufacturer : BROILTECH

Material of construction:

Enclosure                   : PA66 + GF

Rotor                          : PA66/POM/PPS

Shaft                           : Hard Stainless Steel-316

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

Accuracy (standard installation position) : +/-  0.5 or 1%  FSD

Repeatability : 0.05%                                                                                                             

Maximum working pressure : 2.5 MPa                                             

Fluid &Ambient temperature: -40 to 120 Deg. C

Connection: Thread (M)
 

 1) 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.

2) Display with 4 to 20 mA Output

Power voltage: 24 V DC

Output signal: 4 TO 20 mA
