Hi,
WOW 13 posts, and the OP hasn't returned in three days.
- What is the fluid you wish to measure the temperature of?
- Is the fluid under considerable pressure?
- What is the pipe material?
- Do you need the temperature sensor to be in the fluid or on the pipe wall?
- How long would the leads of the sensors be, between the arduino and the sensors?
- Why does the display have to be visible from 15 to 20feet.
- If you could move the display closer, would a smaller display be better.
Now we wait...
Thanks.. Tom..
well he said that he can put the sensor into the flow. so we do not need to concern ourselves about pipe materials, flow rates or even pressures. we have to assume that going to a trade show, the gent knows how to pipe up a thermowell.
ALL he is asking for really, is how to display so people walking by his both can see the values from about 20 feet back.
not sure why of the 13 posts, no one is trying to address his actual question.
