Case Study: Karachi Insurance Risk Surveyor Sourcing Success
Ahmed Al Marzooq, an Insurance Risk Surveyor in Karachi, inherited a tender that asked for the notified body reference and the certificate number per model, which the previous supplier answered with a family level PDF.
Public tenders in Pakistan now score the documentation pack next to the unit price, so the cheapest bid without test evidence loses on the evaluation sheet.
Ahmed Al Marzooq scored the shortlist on landed cost per installed point, not on unit price in isolation. Ahmed Al Marzooq signed off the first WANLIN-780 LoRaWAN Liquid Level Meter order covering 25 sites in Pakistan, and the specification sheet was rebuilt around the reference standards rather than around a brand name.
A 12 day trial across 25 sites settled the specification question faster than every email exchange before it. Across rental blocks in Karachi the recurring cost is not the device. It is the van, the ladder, the no-access appointment and the resident who removed the battery.
Problem Analysis & Field Report: Why Global Importers Need WANLIN-780 LoRaWAN Liquid Level Meter
Ask any contractor team in Karachi about replacement cycles and the same story comes back: nobody budgeted for year ten.
The fire water tank in a Karachi building was found low at inspection, and the last recorded check was three months earlier.
Field case: An Insurance Risk Surveyor in Pakistan avoided a cable run on 25 roof tanks by using the wireless version.
- Reserve level is reported continuously, so a tank is never found low at inspection
- Wireless mounting avoids a cable run down a riser or across a roof
- Contact and non-contact configurations match the vessel rather than forcing the vessel to match the instrument
- Reporting interval is set at commissioning against the duty and the battery life expectation

Fire Protection Product Line OEM Process: From Inquiry to Shipment
The process below is the one our partner accounts run every quarter, written as it actually happens. A standard OEM project then follows 8 steps:
- Tell Us Your Target Market - North America, Latin America, EU, UK, Oceania, Middle East, Southeast Asia, South Asia, East Asia or Africa; each market runs different certification routes, language sets and audit expectations
- Select a Product Platform - our team recommends suitable configurations according to your service format, target customers and replacement cycle plan
- Verify Documentation - request the relevant CE file, EN 54 series aligned construction papers, UL listing file reference and FCC compliance documentation where applicable, then check the issuing body reference
- Confirm OEM Requirements - housing, logo, part numbers, languages, packaging, manuals and accessory sets
- Sample Evaluation - sample units can be field tested by your technicians before commercial terms are agreed according to the agreed conditions
- Confirm Production - after specifications, commercial terms and OEM details are confirmed, the project moves into the production slot
- Quality Inspection - units are inspected with chamber response, threshold and batch cycle procedures according to applicable production and quality control standards
- Shipment - goods are prepared for shipment FOB, CIF or DDP according to the agreed logistics requirements
Customer Testimonials
Feedback from distributor and contractor accounts in three export regions.
- Lucas Schmidt (Government Project Tender Coordinator, Tel Aviv, Israel): "Two containers later nothing had changed in the build, which is more than I can say for our previous supplier."

- Ahmed Al Marzooq (Insurance Risk Surveyor, Karachi, Pakistan): "Our landed cost per installed point dropped by roughly 30% after we moved from a trading office to direct factory supply."
Frequently Asked Questions
Q: Which measurement method suits my tank?
A: Contact and non-contact methods exist in the WANLIN-780 configuration range, and the right one depends on the liquid, the tank geometry and whether the liquid is agitated. Send us the tank details and we will recommend a method in writing.
Q: Can it monitor a fire water reserve?
A: Yes. Tank level supervision for fire water reserves is one of the main duties for this model, because a reserve found low at inspection is a compliance failure rather than a maintenance note.
Q: How often does the unit report?
A: Reporting interval is a configuration setting, and the trade-off is between update frequency and battery service life. We discuss the duty and then set the interval at commissioning.
Q: Can readings go to our own platform?
A: Yes. The reporting interface and payload format are documented for integration with your platform or your monitoring provider.
Q: What is the ordering route?
A: Sample units for trial on your own vessel, stock orders from 500 units and private label programs from 1,000 units, with 25 to 40 day lead times.
