pump pressure loss notification

[VAV]

Does anybody know of a fairly simple control that you can monitor a condenser water pump on the roof to send a text or email alert if the pump looses discharge pressure?

Johnson wet DP switch? Can be a little finicky to tune on some small pumps.

I understand the Pressure differential switch part of it. I was wondering about the part that sends out the email or text? The building ha no EMS or BMS in it. so nothing tie it too. Thx

You have a chiller and no BMS at all?

Is there an existing alarm system in the building? That can do it too.

Sensaphone is the easy, quick solution.

If you want to spend less money, spend more time (investing in yourself), and are into DIY, check out Adafruit... here's a good starting place:

I assume this is for a large cooling tower?

Does the building have internet? You can use a Pelican Wireless wireless gateway and their power control module which gives you 5 sets of dry contacts. https://www.pelicanwireless.com/wp-c...-PM5-1-min.pdf
