The JJY-YLB4S-47 is a 4G solar radar level gauge for remote pipes, tanks and open channels where no power or cable run exists. The built-in battery keeps it measuring for about 60 days without any sunlight, a 5 V / 7 W solar panel recharges it in the field (or top it up over any 5 V supply), and the 4G modem with a global SIM reports from 100+ countries — ±2 mm accuracy over a 40 m range, IP68 sealed. Ideal for off-grid private water tanks, plantations and rural utilities, and eligible for FORM E 0% import duty into ASEAN.
The internal 15 Ah battery carries the gauge through about 60 days of overcast or shaded weather with no solar input at all — so a week of rain or a north-facing mounting spot never takes the sensor offline. Data upload interval is configurable from 5 minutes to 2 hours to trade reporting frequency for battery life.
The LTE modem (TDD B34/B38/B39/B40/B41 + FDD B1/B3/B5/B8) works with a global SIM card covering more than 100 countries — one gauge, deployable across export projects and multi-country fleets without changing hardware. Data uploads encrypted over HTTP / MQTT, straight into your platform or ours.
The 5 V / 7 W solar panel (1.7 m cable) keeps the battery topped up under normal daylight. No sun or panel in the wrong spot? Charge over any 5 V supply — a phone charger, a power bank or a site DC outlet. Power in, then forget about it.

No. The built-in 4G modem reports over HTTP / MQTT straight to your platform or ours, with no cable run back to the office. Tell us your SIM preference (we can pre-install a data SIM or leave it open for your local carrier).
Yes. Using the RadarBLE app, we configure the transmitter’s Modbus protocol to match the protocol your PLC already uses — the existing PLC program stays untouched. You can also commission it from the RadarBLE app / mini program.
It uses an M20×1.5 thread with a G2″ boss and a 2-inch nut, and runs on DC 8–14 V. The IP68 sealed housing is rated −40 °C to 75 °C for outdoor and flooded installations.
One unit. There is no minimum order quantity: a single evaluation unit, a 20-unit trial order and a 500-unit batch are all accepted. Quantities under 20 units ship directly from stock; 20–500 units are scheduled into production.
1–20 units: dispatched within 2 working days from stock. 20–500 units: 1–4 weeks for a scheduled production run, depending on the current schedule. Customised versions follow exactly the same schedule — customisation does not extend the lead time.
Measuring range, M20×1.5 / G2 mounting, communication protocol and solar-panel cable length are all customisable. One free sample is provided — the buyer covers the freight.
ISO 9001:2015 (certificate 02426Q00028R101, valid until 2029-01-15). CE certification is in preparation.
Dispatched within 2 working days of payment confirmation.
Depending on the production schedule: 1 week when a run is already planned, up to 4 weeks at peak, followed by calibration, 48 h burn-in and waterproof testing.
Customisation adds no extra lead time.
Tell us the tank, the medium and the quantity — we answer with a quotation, datasheet and lead time within two working days.
