Rochester Sensors TEK 920
+ Rivio Fleet Dashboard.
The TEK 920 PulseWave is Rochester Sensors' newest non-contact 60GHz radar level sensor, using Bluetooth 5.0 BLE for wireless communication. 1cm accuracy, up to 3m range, unaffected by temperature, pressure, or dust. Pair it with Rivio's BLE gateway to bring all your TEK 920 sensor readings into a live cloud fleet dashboard.
What Is the TEK 920 PulseWave?
PulseWave is Rochester Sensors' latest radar platform — a 60GHz non-contact sensor that installs on top of the tank without any drilling. Its performance is unaffected by temperature, condensation, pressure differences, or dust inside the vessel. It communicates wirelessly over Bluetooth 5.0 BLE, with a wired analog voltage output option.
📡
60GHz PulseWave Radar — 1cm Accuracy
High-frequency radar provides 1cm measurement accuracy over up to 3m of range — ideal for small tanks, chemical vessels, and high-precision applications.
📶
Bluetooth 5.0 BLE Wireless
BLE 5.0 communication removes the need for cellular SIM cards at each sensor. A single Rivio BLE gateway can collect data from multiple TEK 920 sensors in range.
🌡️
Immune to Temperature, Pressure & Dust
Radar technology is unaffected by condensation, temperature swings, vapour, or dust — conditions that challenge ultrasonic alternatives.
🔋
Up to 10-Year Battery Life
Low-power BLE and efficient radar electronics deliver up to 10 years of battery life in the field — eliminating frequent maintenance visits.
How TEK 920 + Rivio Works
01
TEK 920 Measures via 60GHz Radar
Installed on the tank top, the TEK 920 fires a 60GHz radar pulse and calculates level to 1cm accuracy — without touching the liquid inside.
02
BLE Transmits to Rivio Gateway
The sensor broadcasts its reading over Bluetooth 5.0. A Rivio BLE gateway on the vehicle, trailer, or facility picks it up and pushes data to the cloud over LTE.
03
Rivio Shows Your Full Fleet
Every TEK 920-equipped asset appears on the Rivio live map with level %, GPS position, job state, alerts, and run history — all in one place.

Where TEK 920 + Rivio Is Used
🧪
Chemical & Lab Tanks
1cm radar accuracy suits precise chemical additive tanks, lab reagent vessels, and small specialty tanks where level precision matters.
💧
Water & Additives
Non-contact measurement of water storage, chemical treatment additives, and industrial process tanks in facilities with local BLE coverage.
⛽
Fuel & Lubricant Storage
High-accuracy radar monitoring for diesel day tanks, oil storage, and hydraulic fluid reservoirs — where foam or vapour would affect ultrasonic sensors.
🚛
Truck & Trailer Tanks
Mount the TEK 920 on a liquid tank truck or trailer. Rivio's BLE gateway on the vehicle picks up the reading and sends GPS + level to the cloud.
🏭
Industrial Process Vessels
Suitable for process tanks, batch vessels, and intermediate storage in manufacturing environments with challenging temperature or pressure conditions.
📋
High-Accuracy Inventory Control
1cm resolution across many tanks enables precise inventory accounting — especially valuable in chemical distribution or pharmaceutical settings.
TEK 920 + Rivio FAQ
What is PulseWave radar technology?
PulseWave is Rochester Sensors' 60GHz short-range radar platform. It pulses a radar signal and calculates distance to the liquid surface to 1cm accuracy over up to 3m, without being affected by temperature, pressure, vapour, or condensation.
Does the TEK 920 have its own cellular connection?
The TEK 920 communicates over BLE 5.0, not cellular. To get data to Rivio's cloud, a Rivio BLE gateway on the vehicle or facility aggregates the BLE readings and forwards them over LTE.
What is the range of the BLE signal?
Bluetooth 5.0 provides up to approximately 100m line-of-sight range indoors. For vehicle mounting, the Rivio gateway picks up the TEK 920 when within BLE range.
Is the TEK 920 available in a wired version?
Yes. In addition to the BLE wireless model, the TEK 920 is available in a wired version with analog voltage signal output — suitable for fixed installations where a wired connection is preferred.
How does TEK 920 compare to TEK 880?
Both are radar sensors. The TEK 920 communicates over BLE (needs a gateway for cloud integration) while the TEK 880 has built-in cellular. TEK 920 also has 1cm accuracy and is Rochester's newest radar platform.
