^1 To ensure stable detection, it is recommended to use a pipe inner diameter that is at least equivalent to the inner diameter of this product. ^2 Gases that transmit ultrasonic waves. Measurement may be unstable due to the pressure inside of the pipe and the type of gas. ^3 This value is guaranteed by KEYENCE inspection facilities. Errors will be introduced by factors such as the condition and type of pipes as well as the temperature and type of gas. ^4 This specification is valid when sufficient straight sections of pipe are provided and the flow velocity distribution is stable. This value does not take into account the effects of fluctuations in flow velocity distribution due to facility factors. ^*5 Accuracy improves with longer response times. As a rule, this is by a proportion of √(250 ms/response time)x.

All PLC Direct products come with a 1-year warranty. The warranty is issued by PLC Direct. Warranty coverage commences at the date of purchase. The warranty is for mechanical defects or failures not caused by human factors including but not limited to (a) incorrect installation, (b) operating the unit in sub-optimal conditions or in scenarios not recommended by the manufacturer, (c) poor unit maintenance, etc. The warranty does not cover programming or software related issues.

If the product is eligible for PLC Direct’s warranty coverage and the customer encounters an issue with the product, we will request the item is shipped to us for diagnosis and examination. Regardless of the cause of product issues, the customer will bear responsibility for the cost of shipping the unit to PLC Direct for evaluation. Where the unit was damaged by human factors, we will offer a repair or replace quote; in cases where damage was caused by human factors, the customer is responsible for the cost of shipping the repaired/replaced unit from PLC Direct to the customer. Where the unit was not damaged by human factors but is covered by PLC Direct’s warranty, we will repair or replace the unit at our cost (or, in rare cases, refund you your purchase); in such cases, PLC Direct will bear the cost of shipping the repaired or replaced product back to the customer. It is up to PLC Direct’s discretion whether to repair, replace, or refund the customer in such cases.

"Fast service for obsolete parts"

Increasingly PLC/ HMI control platforms are becoming obsolete and parts are no longer supported, however PLC Direct had the HMI we needed and fast shipping for our system to get back online!

"Helping us move projects forward"

With supply chain issues increasingly affecting our business, PLC Direct has been there for us to supply the PLC products we need, when we need it. If they don't have it readily available, they find it and provide it quickly and reliably. This has helped us move forward with several projects that would have otherwise taken us many, many months to complete.
