![]() ![]() ![]() Basic functions and properties of the flow meter Connection of sensors and display of measured values After transferring to the server, the measured data are stored in the database and are accessible to authorized clients at any time via a standard web browser. The flow meter supplemented by a GSM module (telemetry stations Q2-G, Q2 / KDO-G) or a Wi-Fi module (telemetry stations Q2-W, Q2 / KDO-W) can use data hosting set up on the manufacturer's server. The robust design of the metal housing with high IP67 protection and a number of self-diagnostic procedures contribute to the high operational reliability of the flow meter. The measured values are stored in the internal memory of the device and can be transferred to the database to the server via the internal GPRS module (telemetry station Q2-G). The Q2 / KDO velocity flowmeter uses a KDO probe to calculate the flow, which works on the Doppler principle of measuring the flow rate of a liquid. The flow can also be calculated on the basis of the table-dependent dependence between the level and the flow. The instrument contains consumption equations for all common types of Parshall or Venturi troughs and for standard specific overflows. The four-channel flowmeter Q2 contains inputs for the connection of ultrasonic, radar or strain gauges and, based on predefined consumption equations (dependence between the level height and the instantaneous flow for a given specific trough or specific overflow), continuously calculates the instantaneous and cumulative flow.
