I discovered on Friday, by chance, during a visit to the CAT office in Chiang Rai, that the mast that provides CDMA coverage to the Mae Yao area and located in Huay Pra Khan is probably being switched off and decommissioned on Monday 25th July.  No notice given.

They say they will locate the transceivers to another mast in the area.

Therefore if you use CAT CDMA and currently get a signal from the mast in Huay Pra Khan, you just may not have Internet service after 25th July. If this is the case, and your signal goes to ZERO, go to the CAT office and let them know so they are aware of the impact of this action.

The reason for this ?  I have had two explanations.  
1)  The land on which the mast is located has been sold and the new owners will not renew the lease to CAT, and told them to remove it.  
2) Some local residents lodged a complaint with a Government environmental agency in Bangkok stating health concerns from the radiation - apparently pre-empted by an article in the Thai press relating to electromagnetic radiation from transmission towers.  That agency has instructed CAT to switch off the tower.

If it is the latter - a lot of scrap metal will be for sale soon - maybe countrywide !!

All a bit sad really - as I finally got a good signal and speed from that mast after a lot of visits to CAT - and now probably have to start all over again

Hoping that they do not switch it off  !!

I'm looking for ideas to prevent a well pump from running when it has lost prime.

The pump fills a 6 cu. m. storage tank next to it, so very little pressure on the output side as it only lifts the water about 3 meters to the top of the tank.

I assume a low pressure cut out switch probably will not do the job.

Is there any way of detecting flow of water on the output side of the pump into the tank and switching off the pump if flow not present, maybe after a time delay to allow the pump to start ??

Thanks in advance  . . .
