XSR20FC Flow (Heat) Compensation Accumulator Recorder

Product Features

◆ This instrument has the function of compensating for changes in fluid temperature and pressure. When measuring flow rate, if the temperature and pressure of the measured fluid deviate from the design values, it will cause certain errors in the measurement results of volume flow rate and mass flow rate. This instrument has the function of compensating for the temperature and pressure of general gases, superheated steam, and saturated steam. The instrument has three input quantities: flow, pressure, and temperature, which can eliminate the adverse effects of temperature and pressure changes on flow measurement results;

◆ 0.2%F.SHigh precision and equipped with calibration and digital filtering functions can help reduce errors in sensors and transmitters, effectively improving the measurement and control accuracy of the system;

◆ Temperature, pressure, uncompensated instantaneous flow rate, and compensated instantaneous flow rate can be alerted with upper and lower limits through parameter selection;

◆ Complete network communication function. Having standardRS-485TheRS-232TheRS-422TheBCD-Code interface for high-speed and efficient bidirectional data exchange with computers. Capable of remote debugging, diagnosis, and data collection. Provide technical support for testing software, configuration software, and application software;

◆ Equipped with a printing interface and printing unit with a hardware clock, it can achieve manual, timed, and alarm printing functions. If an intelligent printing unit is selected, multiple instruments can share one printer;

◆ The power outage recording function can record the total power outage time, number of power outages, and the last one8 The real-time time of power outage and power on.

◆ Accurate measurement Fixed classification signal input, maximizing accuracy, resolution, and anti-interference ability based on the characteristics of each signal, using the United StatesCS5523 A/DConverter ensures measurement accuracy and speed

◆ 97formula Adopting internationally recognized methodsLAPWS-IF97Formula for calculating steam density
