General Information Please note that the following installation conditions must be obeyed: Pressure requirement: MAP16. Electromagnetic environmental class: E1 Mechanical environmental class: M1 Mechanical environmental condition: B Installation requirement: There must be a minimum of 25 cm between signal cables and other installations. Note: Seal or any safety marks on the meter must not be damaged or removed and doing so will void the warranty and calibration of the meter. 2. Technical Specification 2.1 Flow Sensor The flow sensor is a device used to measure the velocity of flow by using the principle of ultrasound. It can measure the average velocity along the path of an emitted beam of ultrasound by averaging the difference in measured transit time between the pulses of ultrasound propagating into and against the direction of the flow. The flow measurement is based on an acoustic wave time of flight principle. The flow meter body is equipped with 2 ultrasonic transducers facing 2 acoustic reflectors. Flow sensor data: Manufacturer Bove Type BECO Y Accuracy class Class 2 MAP 16 bar Max pressure loss ≤ 63 kPa Max admissible temperature (optional) 30°C / 50°C / 70°C Limits of temperature (Θmin and Θmax) (optional) 0.1-30°C / 0.1-50°C / 0.1-70°C Installation requirements No straight pipe required Basic mounting orientation and other specified orientations 360° Mechanical environmental condition B Electromagnetic environmental class E1 Mechanical environmental class M1 2.2 Calculator Copyright© 2023 Bove Intelligent Technology Co., Ltd The calculator is a device that calculates the flow volume consumed based on signals from the flow sensor. It’s also the meter's control, display, and data store part. Calculator data: Manufacturer Bove Mechanical environmental condition …
