For the water system conditions, you may find the new WestTech

gage of interest .  Check out

Here is some additional information that I got as a reply to my inquiry
below.

I was wondering if it is possible to order just the coolant system
monitoring gauge and its associated electronics.  If so, how much does it
cost?

RESPONSE:

We offer the coolant system gauge and its associated electronics for $875.

I presume that you would like to use this gauge on a different engine or
application.

Please keep in mind that unlike our cooling system, the overwhelming
majority of liquid cooling systems on engines do not produce any
appreciable circulation pressure. Circulation pressure is not system
pressure - it is just the pressure that is produced by the water pump
circulating the coolant. Our gauge specifcally substracts system
pressure so that a true circulation pressure is indicated. Most
circulation pressures are under 2 psi, if that much. If such is the case
with your application it is unlikely that our coolant system gauge will
be of much value. However, if your application does have at least 5 to
10 psi of circulation pressure than our gauge could be of significant
benefit.

Sincerely,
Bob Atkins

"Circulation pressure"? Sounds like the pressure drop as the coolant
circulates through the block and the rest of the system. 
What is so unique about that? All liquid cooling systems do that.
Sounds like BS to me.
