What are the types and functional characteristics of NHRs flow integrators? What are the types and functional characteristics of NHR flow integrators? At present, there are NHR-5600/OHR-E600, NHR-7600/G600, NHR-5600 functional features: Overview NHR-5600/5610 series flow/heat accumulation control instruments are used to collect, display, control, remotely transmit, communicate, print and process various signals such as on-site temperature, pressure, flow rate, etc., forming a digital acquisition system and control system. The flow accumulation control instrument is suitable for flow accumulation measurement and control of liquids, general gases, superheated steam, saturated steam, etc; The heat accumulation control instrument is suitable for heating systems and heat exchange systems such as plumbing, and can achieve online measurement of heat and mass transfer, providing a basis for enterprise energy management, energy consumption measurement, and technical economy. ★ Dual screen LED digital display, with an extremely wide display measurement range, can display the entire five digit instantaneous flow measurement value, temperature and pressure compensation measurement value or inlet and outlet temperature measurement value, flow (differential pressure, frequency) measurement value, and the entire eleven digit cumulative flow measurement value; The measurement accuracy is 0.2%, and the cumulative accuracy is 0.1%. ★ It has 37 types of signal input, and users can freely set the input type according to their needs. It can be matched with various differential pressure signals (orifice devices), linear signals (electromagnetic flow meters), and pulse signals (vortex flow meters), and can freely choose multiple compensation methods (temperature compensation, pressure compensation, temperature and pressure compensation, etc.). ★ Using the lookup table method for density compensation, it can automatically perform high-precision integration control on superheated steam and saturated steam. It has multiple built-in flow integration formulas, suitable for various measurement scenarios, and has an automatic calculation function for flow coefficient K. ★ Simple fault-tolerant function: When temperature and pressure compensation or inlet/outlet temperature measurement signals are abnormal, they can be switched to pre-set operating constants for compensation calculation. Specially designed WDT circuit, power on reset circuit, and power-off data protection circuit ensure that the instrument operates normally when powered on; Equipped with a built-in 3.3V dry battery, data is not lost during power outages. No backup power supply is needed for data protection during power outages, and the protection time is not less than 3 years. ★ It can perform quantitative/batch control on the measuring medium (with start, stop, and reset functions). ★ Can be equipped with two analog transmission outputs. ★ Supports RS485

5, RS232 serial interface, using standard MODBUS RTU communication protocol. The instrument can be equipped with RS232C printing function, with manual, timed, and alarm printing functions. ★ Equipped with DC24V power supply output, it distributes power to the on-site transformer and permeator. ★ Input, output, power supply, and communication are separated by optoelectronic isolation technology. ★ Parameter setting password lock, parameter settings are permanently saved when powered off, and have the function of restoring the original syste
