High Performance Precision Flow Meter Turbine Type With Ss304 Material
Function:
0.8--30KHzequal precision frequency measurement; width of the pulse can be displayed
Double circuits 12 digits DA output; DA output value can be arbitrarily set.
Double circuits alarm output, the parameters monitored can be arbitrarily set; higher and lower alarm can be arbitrarily
set.
Three circuits’ 12 digits input (temperature, pressure, battery voltage); 0-1000Hz frequency output; programmable
pulse output; time, instant flow rate and accumulative flow rate can be recorded; overall power consumption 200uA
Setting:
1. Long press Set key (3 seconds). When displaying 555, by pressing Inc & Shift key and enter corresponding
passwords; choose set and enter
2. Press Set to page down and press Shift to page up
3. When want to set parameters in a certain page, press Inc then start to flicker. Then use Inc and Shift to set. After
finishing, press Set and next line begins to fickle. Then set following the above method.
4. After finishing the set of a certain page, long press Set till no blink. This means exiting setting state
5. Shift + Set reset cumulant (need to press when the cumulant is flickering)
6. A menu parameter, factory password85 (B menu can revise this password)
Notice: In order to make sure the parameter setting of the LWGY-C flow meter is not changed at will, we will not provide you
specific setting state and passwords. The flow meter will be equipped with corresponding manual and user can also consult from the
manufacture. For the inconvenience brought, please understand.
