Mopeka Ultrasonic Tank Level Sensors for LPG and Water
Mopeka tank sensors use ultrasonic sonar to measure liquid levels, so they do not need float senders, drilled tank fittings or changes to your plumbing. This collection includes Mopeka Pro Check, PRO200 and TD40 sensors for monitoring LPG cylinders and water tanks. It also includes the displays, collars, bridges and installation accessories that complete a monitoring setup in caravans, RVs, boats, 4WD campers, tiny homes and off-grid sites.
Several sensors in the range are Victron compatible. When paired with a Victron GX device, LPG and water levels can appear on the same dashboard as your batteries, solar and inverter data. This gives you one place to check your system before you leave camp or head offshore.
Sensors in the Range
- Mopeka Pro Check Bluetooth LPG Tank Level Sensor: Dedicated LPG cylinder monitoring that reads through the base of the cylinder, with Victron compatibility.
- Mopeka Pro Check Universal Bluetooth Tank Level Sensor: A flexible Victron-compatible option for water and LPG tanks. Use it with the matching Universal Collar Set for the tank type.
- Mopeka PRO200 12V Bluetooth Ultrasonic Wired Tank Level Sensor: A wired 12V sensor that runs from your vehicle or vessel supply instead of a replaceable battery. It suits permanent installations.
- Mopeka TD40 Ultrasonic Bluetooth Tank Level Sensor: An alternative ultrasonic Bluetooth sensor format, also Victron compatible.
Accessories for a Complete Monitoring Setup
The Mopeka LCD Display shows readings from up to two Pro Check sensors without a phone. The Indoor 2.4GHz Wi-Fi Bridge relays sensor data over Wi-Fi for remote tank monitoring. Where Bluetooth range is limited, the Remote Outdoor Antenna with Magnetic Mount adds a 4 metre lead so the antenna can sit in a better position.
For installation, the Pro Check Universal Collar Sets (water and LPG) help position the Universal sensor correctly. The Tank Check Spacer Pack suits LPG cylinders. Mopeka Sonic Grease (4 pack) helps the sensor couple acoustically with the tank surface for consistent readings.
How to Choose the Right Mopeka Sensor
Start with the liquid and the tank. For LPG cylinders, the Pro Check LPG sensor is the dedicated choice. For water tanks, or for a mix of tank types, the Pro Check Universal with the correct collar set offers more flexibility.
Next, consider how you want to power the sensor. Battery-powered Bluetooth sensors are quick to fit and move. The PRO200 12V wired sensor suits owners who prefer a fixed installation with no battery changes.
Finally, decide how you will view the data:
- Phone app: View readings directly over Bluetooth.
- LCD Display: Check up to two Pro Check sensors at a glance.
- Victron GX: Combine tank levels with your energy system data.
- Wi-Fi Bridge: Monitor tanks remotely.
