I want to design a 1000 bbl water tank with automatic level controls. Can anyone suggest a setup / manufacture(s)so that I can design the system without hiring another engineer. I know, I need to degign for 10,000 bpd at less than 150 Psi, not much head. I want a fail safe system with electronic alarms

Go to the API documents (IHS has the contract for distribution and they're at I think the one you want is API 11A, but I'm not positive of that.
I think you'll find that an API standard 1,000 bbl tank comes in two diameter/height combinations. Both of them are rated at something around 0.5 psi (think about it, 1/2 psi spread over a 15 ft diameter 12,000 lbf). At 150 psi you would have to design a standard diameter tank to resist almost 2 million lbf.
If you're looking for a 10,000 bbl/day pressure vessel the references are different.

Generally, the tank and the control system would come separately. Tank companies don't necessarily know anything about controls. As David says, you can use a standard API 12D tank if you want, or you could use AWWA D100 or API-650 App. A at about the same price (tank would be field-erected in any case). For water service, you'd generally want the tank epoxy lined.
Probably the best bet on the controls is simply contacting a company (ie, electrical contractor) that specializes in that type of control system.
I'm not sure what your comment about the 10,000 BPD @ 150 PSI means. The tanks mentioned above are all essentially atmospheric tanks. At that flow rate, you may want an oversized overflow on the tank, compared to what you'd see on an oil tank.
What part of the country or world are you in? We can point you to some specific contractors if you're in the right area.

Per API-12D, the H-1000 tank is 21'-6" diameter by 16' high, maximum pressure of 6 oz/ square inch. L-1000 is 29'-9" diameter by 8' high, maximum pressure of 4 oz/ square inch. Design vacuum of 1/2 oz/square inch in either case. API-650 or AWWA tanks could be any desired dimensions.
