Schematic , Layout and pcb prototype for the following:
Water meeter to be able to:
interface to magnetic rotating dial, approx 15mm diameter.
3 coils or reedswitches + tamper switch needs to be mounted to magnetic dial, i will worry about fixture for this.
Have RTC onboard.
Have RS232 connector std pin db conector.
Detect direction of flow, ie wether dial is rotating clock wise or anti clock wise, send alarm code plus date time stamp out thru rs232 port.
Store daily pulse count, send out monthly pulse count to rs232 port or when requested from pc
store last 12 months pulse counts, one total for each month.
if cable is cut between logger and meter alarm code is sent to rs232 port with date time stamp.
if tamper switch is detected then temper code sent to rs232 with datetime stamp.
command to read any of the last 12 months pulse count (if reading the current months pulse count then give me month todate).
please refer to cyble sensor as a means to interface to the meter. [login to view URL]
meter to interface will be similar to Aquadis dn20.
schematic design
pcb design
pcb prototype manufacture
develop firmware
supply prototype
ONLY interesed in person who has expeiences in water flow metering and ONLY people that can complete the projects and supply to me a working prototype. water meter will be supplied by me.
Do not bid if you cannot provide all services.
please send on similar work.
Hi,I am an automation engineer supported by a team of two electronics and one mechanical engineer, Can develop the complete prototype and test it.
REGARDS, Brajesh
We have wide experience with different kind of sensors and interfaces, and we can do it according your specification. Please, contact us by email if you are interested, so we can discuss technical details.
Best regards, Darko.
We can do the Circuit design for the water meter logger.
WE can do the PCB layout.
We can do the Embedded software for the fuctionality of the water meter logger.
We can deliver the working prototypes.
Additionaly we can also do the plastic or metal enclosure ID design in Solid works and then do the RPD protos for an extra cost.
If intrested we can submit you the complete proposal for the project with schedule and payments terms.
