Technical Support

Customers are ESI‘s Number-One priority!
We provide the ability to get fast support through our toll-free number for tech support(800) 886-2511 — and are available Monday-Friday, generally from 8am to 5pm, Central Time. Our certified technicians and engineers can assist with almost any tank monitoring challenge you can imagine.

Our monitors come with a one-year warranty, and maintenance and tech support are generally available for several years afterward (many of our systems have remained in operation for over a decade).  But our products are designed for trouble-free, worry-free operation, and seldom require support or maintenance.  We know what you want:  SYSTEMS THAT WORK !


“I am… very happy with the service…”

Andrew Moseley, Director of Operations
Florida-based oil distributor Flamingo Oil (RelaDyne)

“I have been thoroughly satisfied with the technical abilities and knowledge [of ESI ].”

Brian Golden, supervisor,
national chemical manufacturer ITW Pro Brands

“[Since] our facility Installed the Tank Teller II System [in] 1997… there have been occasional instances in which we required some service know-how.  We have found the staff at Electronic Sensors super supportive, and extremely good at listening to what our issue might be, and in working with us to rectify the situation.

“Even though our equipment more than 25 years old — and there has been personnel changes in the customer support group at Electronic Sensors – they still retain the product knowledge to offer solutions. Best of all, turnaround time for replacement parts and consumables is superb (even in today’s environment) [early 2022].”

Dave Rinefierd, Polsinello Lubricants
regional* distributor of motor oils & lubricants
(*New York, New Jersey, Pennsylvania, New England)

“The customer service and technical support is world class.”

Aleczander Stith, Vt. Plant Manager/Engineer,
