SensoTech announces LiquiSonic OCR analyzer

August 18, 2016 - The LiquiSonic OCR analyzer, by SensoTech, is specifically designed for refrigerant applications, and enables the oil circulation ratio in the refrigerant to be monitored online and directly in the process using sonic velocity measurement. Due to the chemical and physical properties of refrigerants, sonic velocity measurement is ideal for determining the concentration. The LiquiSonic sensor is installed in the pipeline and combined with a pressure transducer. Additionally, two Pt1000 temperature probes are integrated in the sensor, so that from the values sonic velocity, temperature and pressure the temperature- and pressure-compensated oil concentration can be calculated in real time. The measurement accuracy is ± 0.1% m and the sensors are completely maintenance-free due to the robust design.

At temperatures between -30 °C (-20 °F) and 120 °C (250 °F), the sensors can be used in oil/refrigerant mixtures such as polyester oils (POE), polyalkylene (PAG), polyalphaolefins (PAO), hydrofluorocarbons (HFCs) R134a, 1234yf, carbon dioxide R744 or ammonia R717 in various industries like automotive or building air-conditioning. The LiquiSonic® controller displays and stores the real-time information. Via 4-20 mA signal, digital outputs, serial interfaces, fieldbus or Ethernet, the controller can be integrated into the network and control system.
