This looks interesting, do you know if it is possible to measure water depth with it too?

Got the lr4 414d and cables now to install.  I'm thinking about using plumbing heat tape to keep it all above freezing.

Fluke thinks that's a good idea see http://www.fluke.com/fluke/usen/community/fluke-news-plus/ArticleCategories/Electrical/101AppForDistanceMeters.htm

Installed the LR4/Fluke 414D last night just before the snow and it performed perfectly. We received 4.2 inches overnight. The LR4 / Fluke 414D mod is far superior to the LR3 / Fluke 411D. No cable bending and shoving and tucking like the LR3/Fluke 411D.

Good luck with the project.

Cheers

I hope to get at it tomorrow.  I bought 3 feet of heater tape today for inside the box.  The only trouble is they say it is a torx T8 to unscrew the meter but the one I bought today is too large so it must be a T7 or T6.  It is snowing here now and due to snow several more times this week so I'll soon find out how well it works.

It's a #6 torx. All Porcupines instructions are incorrect. I keep meaning to send Richard a note and I keep forgetting. If you live near a Sears store they have nice torx for I think $3.99.

Thanks MikeyM.  I went outside on Wed. to blow some snow and get ready for the install and slipped on the ice.  I've never been  this sore in my life!!!!!! X-rays show no broken ribs but I'd swear everyone was broken.  It was all I could do to type this.

Darn near killed myself yesterday but I think I have the sensor installed and working correctly.  Are the php graphs for snow available?  If it is where can I grab a copy?

thanks

Hey Guys,

Been very intrigued by this project.  I read the specs and it seems that the cold weather may affect the readings some.

Has anyone been having issues with the cold affecting the readings?

I glued a 3 foot piece of heater tape on the inside of the box and haven't had any problems.  It's been quite cold here zero deg F and colder lately.  I'm using the lr4 and 414d

Hi

I'm using an 1157 automotive bulb in my enclosure with a button type thermostat and haven't had any problems. I added the heater as the Fluke 411D and 414D are only rated down to 32 def F (0 deg C). My enclosure temperatures can be seen at:

Thanks Guys I will probably go with a similar design to what I am using in my rain gauge (just with a little less power).

Still debating if I am going to install it this year or next year...

Guys,

I have finally taken the plunge to Laser Snow Depth measuring, and boy does it work well.

Just a few questions.

Are you guys running one of the Porcupine demo programs 24/7 to collect the data with WD (1 wire)? What is your upload rate back to the computer from the Range Finder? Have you had any problems with either Porcupine demo programs or the 1 wire program stopping causing it not to receive data? Are you guys turning the laser off when not in use?

I haven't installed a heater yet, and the sensor seems to be measuring without issue (even this weekend at -14F).

Thanks guys,
