WELK Level supports model selection, configuration, export packing, OEM documentation and after-sales troubleshooting for radar, ultrasonic, hydrostatic, magnetic, guided wave radar and level switch orders.
Medium, range, vessel dimensions, pressure, temperature, connection, output, quantity and files are checked for completeness.
Day 0The requested model is compared with process conditions. If the technology looks unsuitable, WELK suggests an alternative with reasons.
1-2 business daysPrice, lead time, configuration, accessories, document package, packing and shipping terms are confirmed before production.
After technical confirmationAssembly, parameter setting, wiring, range/output checks, appearance review and packing preparation follow the confirmed order.
Per order scopePacking photos, shipment documents, calibration records if requested and after-sales guidance are provided according to the order.
Before and after dispatchSend medium, measuring range, tank height or vessel drawing, pressure, temperature, process connection, output signal, power supply, hazardous area requirement and quantity. Photos of the installation point are helpful for radar, ultrasonic and magnetic gauge selection.
WELK reviews the application before quoting. If information is missing, the quotation will state the assumptions and the items that must be confirmed before production.
Level instruments are packed to protect electronics, probes, antennas, chambers, floats, cables and accessories during export transportation. Packing method is selected by instrument size and order quantity.
For configured orders, WELK can provide packing photos, carton or crate marks, manuals, calibration records and shipment documents according to the confirmed order terms.
OEM support can include private label, model coding, nameplate information, measuring range, process connection, output signal, housing color and documentation format. ODM work is reviewed case by case because sensing principle and safety approvals must remain correct.
Share target market, required documents, annual demand and any existing model reference. WELK will confirm what can be customized without changing the technical limits of the instrument.
After shipment, WELK supports installation and wiring questions by email or WhatsApp. For troubleshooting, provide product label, order reference, wiring photo, process conditions, display reading and output signal status.
Quality claims are reviewed with photos, videos, calibration information and site conditions. The response may include wiring guidance, parameter review, spare parts, replacement or return analysis depending on the case.
Yes. WELK reviews the process conditions and can suggest radar, ultrasonic, hydrostatic, magnetic, guided wave radar, DP or switch alternatives when needed.
Yes. Request calibration records at the RFQ stage so the document package and inspection workflow are included in the order.
OEM labels, model codes, manuals and packing marks can be reviewed for suitable orders after the technical specification is confirmed.
Buyer-arranged SGS, BV or similar inspection can be coordinated when it is agreed before production or shipment.
Provide order reference, nameplate photo, wiring photo, display reading, output signal status, process conditions and a short fault description.
Attach the medium, vessel dimensions, process connection, output signal, installation photos and old datasheet if available.
Uploaded reference files are included with the inquiry. For larger CAD packages, reply to the confirmation email or send them here:
