Product details
1、 Overview:
IC card ultrasonicHeat meterIt's in ultrasoundHeat meterOn the basis of this, a prepaid function has been added, and users need to pay the heating fee in advance for normal heatingIC card enables valve opening and supports multiple remote transmission methods, as well as remote meter reading and valve control. It has the advantages of not being limited by geographical building environments, stability, reliability, and low maintenance costs, making it easy for heating units to manage and maintain heat meter reading and charging control,Suitable for household heat (cold) metering project applications.
2、 Main features:
·Adopting ultrasonic flowmeter, the body pipe section is a straight through structure, with no moving parts, no wear, not easy to block, and low pressure loss, especially suitable for domestic use
The heating water quality and long-term operating environment inside;
·Powered by low-power lithium batteries, with a simple structure and a lifespan of over 6 years;
·Measurement function, using imported high-precision computing chips with high measurement resolution and accuracy;
·The data display and storage function can achieve operational data storage, and historical records can be stored for up to 24 months;
·It can achieve prepaid management, effectively eliminate phenomena such as arrears and refusal to pay, support remote valve control function, and its authority is higher than IC card authority;
·The lifespan of the switch valve can reach over 60000 cycles.
·Multiple communication methods supportedMBUS、RS-485、 Infrared, wireless interface, and multiple communication protocols.
