In short: The WANLIN-780 is our wireless liquid level meter for tanks, reservoirs and fire water storage, supplied in LoRaWAN, 4G LTE and 433 MHz versions. Wanlin Fire is a wireless fire alarm system manufacturer and export supplier in China, covering wanlin-780 lorawan liquid level meter plus the wider wireless detection, alarm, control and monitoring range for OEM, ODM and private label programs. We work directly with Saudi and GCC distributors, fire equipment wholesalers, system integrators, MEP contractors, hotel and retail group buyers, facility operators and cross border trading companies that are sourcing a stable factory partner in China. What changed: about 30% better margin on the accessory basket alone through factory direct sourcing, per-model documentation, per-model test files and flexible MOQ with long-term partner stock programs. The technical review lasted 13 days and included a dust chamber trial in one plant room that nobody had planned for.

Hessa Al Dossari, a Saudi Construction Procurement Manager from Riyadh, walked into a kitchen fit-out where the insurance surveyor had already rejected the first specification in writing.
Wage and access costs in Saudi Arabia put installation labour at the top of the project cost sheet, which redirected the buying conversation in Riyadh towards products that cut install hours.
The decision came down to four things: documents that match the model, a production slot that holds, spares that ship later and one person who answers technical mail. Hessa Al Dossari signed off the first WANLIN-780 LoRaWAN Liquid Level Meter order covering 23 sites in Saudi Arabia, and the specification sheet was rebuilt around the reference standards and the radio plan rather than around a brand name.
From first enquiry to confirmed order took 13 days, with half of that spent on certificate verification rather than commercial terms. For a distributor in Riyadh the decision meeting is short. Two columns on one page: landed cost per installed point against the risk of a rejected acceptance walk.
The expensive part of a failed detection scheme is never the hardware invoice. It is the repeat visit and the re-inspection fee.
A fire water tank at a Riyadh industrial park was found low during a pump test, and nobody could say for how long it had been low.
Field case: A compound in Riyadh showed its water reserve on demand during a Civil Defense walk, which closed a finding from the previous visit.
Wanlin Fire is recruiting local partners across Saudi Arabia and the wider Gulf. Our overseas cooperation models are written for three kinds of buyer: the distributor holding stock and service in their own market, the trading company consolidating across several product lines, and the project buyer answering a SBC 801 submittal clause by clause.
Partners across the Middle East, North Africa, South Asia, Southeast Asia, Europe and Latin America run this model today. Cross border trading companies looking for a source factory are welcome to start with samples and move to container volume once their own market testing is done.
Every unit in the line shares a service philosophy: respond early, nuisance rarely, and stay maintainable across a full replacement cycle. The WANLIN-780 is our wireless liquid level meter for tanks, reservoirs and fire water storage, supplied in LoRaWAN, 4G LTE and 433 MHz versions.
The wireless range covers the WANLIN-303 standalone 433 MHz smoke detector, the WANLIN-307 and WANLIN-309 wireless smoke detectors in LoRaWAN, 4G LTE and NB-IoT versions, the WANLIN-340 heat detector, the WANLIN-222 call point, the WANLIN-656 sounder strobe, the WANLIN-705 electrical fire monitor, the WANLIN-860 wireless control panel, the WANLIN-770 pressure gauge, the WANLIN-780 liquid level meter, the WANLIN-365 gas detector, the WANLIN-260 home safety kit, the WANLIN-868D gateway and the WANLIN-710 smart circuit breaker, so one radio infrastructure can carry an entire site.

Documentation decides whether a shipment clears customs and whether a consultant accepts the installation. Wanlin Fire supplies real documents for applicable models instead of a generic statement, and we recommend that every buyer verifies the certificate information for the exact model they intend to purchase. Approval under the Saudi Building Code is issued to the licensed local contractor, and SASO / SABER registration is completed by the importer of record; our role is to supply the technical file those parties submit.

For importers, Wanlin Fire supports CE, RoHS and REACH documentation with per-model files, EN 54 series and EN 14604 aligned construction papers where the device class applies, and radio compliance documentation for the band plan of the destination market. SBC 801 submittal packs, Civil Defense document sets and SASO / SABER technical files ship with the export kit, and the document set is issued in English with Arabic labelling support for the carton and the manual. Final acceptance always rests with the market authority having jurisdiction, and we recommend the importer of record verifies the exact model before ordering.
The comparison below is the one our partner accounts run before moving from a trading office to direct factory supply.
The Saudi market adds its own requirements to that list. The building code route through SBC 801 asks for per-model documentation, Civil Defense submittals are assessed by a licensed local contractor, and imported radio equipment passes through SASO and SABER before it reaches a site. Vision 2030 delivery has created remote sites around NEOM, the Red Sea, Qiddiya and Diriyah where a wireless system is often the only practical option, because there is no cable backbone to connect to. Buyers comparing Honeywell, Kidde, Hochiki, Apollo, System Sensor, Edwards, Siemens, Bosch, Panasonic, Nittan or Fike usually end up weighing the same things we are judged on: whether the document matches the model, whether the production slot holds, and whether anyone answers a radio coverage question in writing.

The steps below are also the sequence your consultant will follow for a SBC 801 submittal, which is why we run them in this order. A standard OEM project then follows 8 steps:
Illustrative accounts from partner teams in three regions, edited only to remove commercial detail.
A: The sensing element and the measurement range for the version you order are stated on the model datasheet. Tell us the tank dimensions, the liquid and the required accuracy and we will state the configuration we recommend rather than shipping a default range.
A: Fire water storage is one of the main duties, because a suppression system is only as good as the water behind it. The same unit is also ordered for process and utility tanks where the site wants level reporting without installing an instrument cable.
A: High and low level thresholds are set to your tank duty and agreed at specification stage. When a threshold is crossed the unit reports to the alarm layer, which is what turns a tank level into a maintenance or a security response.
A: Outdoor tank mounting is a normal duty, and the enclosure and mounting arrangement are stated in the model documentation. We recommend confirming the siting and the sun exposure with the installation contractor so the mounting position matches the enclosure rating.
A: Yes, the reporting interface and message format are documented, so level data can be routed to your own platform or monitoring centre. Confirm the route at specification stage and we will state it in writing.
What changed: By working directly with manufacturer Wanlin Fire, Riyadh Saudi Construction Procurement Manager Hessa Al Dossari gained 30% margin headroom while keeping competitive installed pricing. With verified per-model documentation, honest specifications, CE and RoHS documentation per applicable model, level measurement duty selected at specification stage, SBC 801 submittal support with per-model technical files, SASO / SABER registration support for the importer of record, private label branding, a radio plan stated in writing and after-sales spare programs, Wanlin Fire became their long-term wireless fire alarm system supply partner in Saudi Arabia. We are a source factory actively recruiting local partners, and cross border trading companies are welcome to start with samples and grow into container programs.
