1. Advancement. Meet the ISO9951 international standard, the length of the watch body is 3DN (DN is the caliber of the flowmeter), and it has passed the high and low level disturbance test;
2. Through strict concentricity test, it has the characteristics of wide flow range, good repeatability, high precision, small pressure loss, low initial flow, etc .; the flow rate ratio can reach a maximum of 1:40;
3. The integrated rectifier is adopted, and the installation requirements on the front and rear straight pipe sections of the flowmeter are low (the front is Greater than 2DN, the rear is 1D), which facilitates the installation requirements of the customer site;
4. Two lithium batteries can be used continuously for more than five years online, and have a battery undervoltage alarm output function, which is more suitable for supporting use with IC card management systems;
5. The flow totalizer can be positioned at any angle (the rotation angle is 270 ). The LCD screen has a viewing angle suitable for human eyes. There is no need to bend the head down deliberately, making the flowmeter reading more convenient and more convenient under various installation conditions direct;
6. The unique time display and real-time data storage function, no matter what the situation, can ensure that the internal data will not be lost and can be permanently saved;
7. It has a standard RS-485 (MODBUS) communication interface function, a standard 4-20mA current output function, and an IC card controller docking function (can be docked with any manufacturer's IC card controller, without requiring the user to replace the management system);
8. With four-line wide-screen LCD display function, it can display parameters such as standard cumulative volume, standard volume flow, operating condition volume flow, medium temperature and pressure, as well as internal power supply or external power supply indication.
