- Want to see our Dry Cake measurement in action? Head to STEP by Pollutec ('Salon de la Transformation Écologique') in Paris on Dec 01-02. Our partner AMCON Europe will be showcasing the OAE-SCOUT Cake Dryness Sensor — our ultrasonic dry cake measurement solution for VOLUTE™ screw-presses. Integrated into the PID controller, it enables real-time automatic adjustment of screw speed, prevents chemical overdosing, and makes 24/7 unattended operation possible. Want to stop by? AMCON Europe can set you up with a free visitor pass (see
- Less than three years ago, we announced our move to a bigger location at Open Manufacturing Campus (Turnhout). Just three years later, we're on the move again. In these past years, Olpas has doubled down on expanding the product portfolio with new product families and measurements - all based on our ultrasound expertise. We've also grown partnerships worldwide (some we can talk about, some not (yet)). Next year, Olpas' focus will be on further expansion, with some new, revolutionary products based on our measurement technology
- A few weeks ago we got the opportunity to test the YDOC.biz datalogger supplied by RMA Hydromet (Thanks Rob Ter Brake!). The Olpas, a concentration measurement instrumentation company water monitoring sensors for Suspended Sediment Concentration (SSC, mg/L) and flow velocity (mm/s), level (mm) and even flow profiling (mm/s) can be connected to the datalogger's RS485 connection. Configuration of the modbus settings is straightforward, but thanks to the demo unit we had we can provide step-by-step instructions to customers using
- The line-up of sensors we designed at Olpas, a concentration measurement instrumentation company is becoming quite something...! From left to right: - Olpas Limpet : Accurate sludge blanket level detector and sludge concentration (TSS, mg/L). Mostly used in wastewater treatment. - Olpas Inline (TUB) sensor: Available for concentration measurements from 1 mg/L up to 75 %DS for everything that moves through pipes (effluent, influent, sludge, slurry...everything!) - Olpas Tentacle: Concentration measurements with a submerged sensor.
- Vamos a la playa! At Olpas, a concentration measurement instrumentation company we've build the Olpas Nerite: a combined Total Suspended Solids (TSS/SSC) sensor with flow velocity and height (0 - 10 000mm) included. Typically, Nerite sensors are installed for long term (years) and data is recorded every 60sec of 10 minutes. To save power, we require our sensors to perform a measurement 'in a few seconds'. Measuring dynamic processes evolving faster than once per minute was not really in the scope of the sensor. However, Yves
- Yesterday we ran our new (still-secret, not on the website yet) wave and current sensor through the big wave flume at Flanders Hydraulics - Waterbouwkundig Laboratorium — h/t Yves Plancke and Tim Aertsens for the waves. Turns out 10cm waves at 3s intervals expose orbital currents faster than our current sampling rate can keep up with, so back to the lab bench for a few weeks and pushing the hardware towards 20 Hz measurement frequency. Slow, unglamorous, very real engineering, but that's how you end up with something that actually
- The current drought in Belgium and Europe results in almost no flow in most small streams. Installed sensors dry out and flowrate measurement are unusable when the level drops below 1cm of water... The dry-out of sensors is quite interesting to see. The pictures show the Olpas, a concentration measurement instrumentation company Nerite flow and sediment concentration sensor after one year of use. The fouling layer is drying and strongly attached. When the water level rises, the fouling layer will become wet and the sensor
- Three of our sensor families made an appearance at Japan's Sewage Works Exhibition 2026 - Japan's largest event dedicated to sewage water technology. Our partner AMCON INC. demonstrated . Cake Dryness sensor (OAE-SCOUT) - optimised for the dewatering screw presses of AMCON Europe (pictured left) . Olpas Tentacle sensor, a submersible sensor for an online measurement of Suspended Solids in sewage and stormwater - with minimal drift and battery powered . Olpas Inline sensor - often used to measure ingoing sludge concentrations
