Hi,
If you'd like someone to answer on this, I think it's good to give a little more background.
As you're getting readings it tells me that it's been hooked up, but not if it's hooked up correctly. Please provide some info on how that's done. Images as well as schematics will be helpful.

I have two networks running in the same area, with the same purpose as yours.
One is running at Channel 13, the other at Channel 58. Works perfectly.

Maybe you have to do some (internet) research on how the screens of smartphones or tablets work. something like this. Ok it's a little bit over the edge for a Arduino, but it gives some direction I hope.

What do you mean by a HE? Human Engineering? Heavy equipment? High End (system)? Happy Ending

This is probably a module that uses CAN-bus as a bus interface. CAN-bus is used in automotive te reduce the number of wires in order to minimise cost. Other busses, used in industry are MODBUS, profibus, etc.
In a way you could see mySensors as a bus system as well as it is wireless 
Could be very beneficial for your challenge: each machine one or more sensor-node(s) - depends on the number of wires you'd like to monitor and the level of multiplexing you'd allow - and a gateway that is connected to a dedicated controller. This controller (I think not one of the controllers as used in the mySensors community) is used to translate the messages to instructions where to repair the yarns.
First thing to do for you is understand your real problem (yarns are breaking) and how you'd like to interact on this.
I think it's good to re-read the remarks @Bogus-Exception made! I strongly suggest you to read that again!

Hi Reshma,
I googled your question ("connect multiple hall sensor to digital") and guess what happened...
this was the first hit I got from google
It may not be exactly what you're looking at, but what I try to explain here is that using google for this may be more helpful than posting it in this forum as I think your question is more related to using arduino in general.

Consider the use of resQ tape. Not sure if this is available world-wide, but the use of it is very versatile.
I've used heat shrink with and without the glue layer inside. Works for some time, but water gets in. Only the resQ tape has proven to keep the joints (cable entries of the connectors) watertight!

above link is an example of a sensor which could be used. Not sure what the level change will be, but the "new law" as you refer to will tell you what accuracy is needed. This sounds to me as a perfect example of a LoRa sensor.
The sensor goes in the bore hole (same as the manual cord measuremens) and stays there. The electronics (4-20 mA preferrably as 1000 ft is quite a distance) can remain at ground level.
If you have any idea what the change of level is in the well, you can easily find the range for the sensor.

Have a look at freescale sensors. i.e. MXP-type sensors. You could ask for samples (they will provide up to 5 pcs. for free). Cost around $15 pcs. normally.
You'd mount such a sensor on top of a riser (air-tight) and when the (sewage) water rises, the air-pocket is compressed proportionally. This is how I measure the ground-water level at my location and it helps me to keep my basement free of water. Works flawlessly!

have you thought about using a jfet?
