JiaJia Eye builds 4G wireless level transmitters for tanks, wells, pipes and open channels where no power, no cable and no site visit are the whole point. The JJY-YLB4S-47 solar 4G radar gauge measures to ±2 mm over 40 m and reports from 100+ countries on a global SIM; pair it with our 4G radar level gauge gateway to watch an entire site from your phone. This is remote tank level monitoring without the wiring bill. It suits off-grid private water tanks, plantations and rural utilities across Southeast Asia.
A wireless level transmitter measures the level locally – by 80 GHz radar or ultrasonic time-of-flight – and then ships the reading over the cellular network instead of a copper wire. No trenching, no RS-485 home run, no technician on site.
For a single tank on a budget, a wired 4-20 mA transmitter is cheapest. For a cluster of tanks within a few kilometres, LoRa / IoT level transmitters extend battery life with a local gateway. For assets that are truly remote, cross-border or moving, a 4G wireless level transmitter with a global SIM wins – it needs no local network at all.
| Factor | Wired 4-20 mA | LoRa + local gateway | 4G + global SIM |
|---|---|---|---|
| Best for | Single tank with power available | Cluster of tanks within a few kilometres | Remote, cross-border or scattered assets |
| Cabling | Signal cable back to the control room | None, but needs a local gateway | None at all |
| Power | Loop-powered from the PLC | Battery, multi-year | Solar + 15 Ah battery, ~60 days without sun |
| Coverage | Limited by the cable run | Local radio range | Anywhere with 4G signal, 100+ countries |
| Dashboard | Local PLC / SCADA | Cloud via the gateway | Cloud on phone or PC, zero site visits |
| Relative cost | Lowest hardware, highest install cost | Mid | Mid hardware, near-zero install cost |
Tell us the site layout and we will specify the right mix – wired gauges, LoRa nodes and 4G units can share one dashboard through the 4G gateway.
The transmitter reads level locally and pushes data over 4G to a cloud dashboard viewable on phone or PC – no on-site wiring to a control room.
No. It uses the cellular network, so as long as there is 4G coverage the gauge reports – no Wi-Fi, no LAN, no cable.
The 15 Ah battery carries the JJY-YLB4S-47 for about 60 days with no solar input; the upload interval is configurable from 5 minutes to 2 hours to trade frequency for battery life.
Use the wired 4-20 mA / RS485 version into an existing PLC, or add a local gateway; the 4G model needs cellular coverage (global SIM, 100+ countries).
Yes. The 4G gateway accepts both digital RS-485 radar / ultrasonic gauges and analogue 4-20 mA gauges on the same unit, so you can add wireless coverage to an existing installation.
OEM / ODM with MOQ 1 and private-label support. FORM E certificate of origin gives 0% import duty into Malaysia, Singapore and other ASEAN markets.
