UF 2900Z series counter - radiation ultrasonic heat meter
a.Overview
UF2900 series of ultrasonic heat meters for household use is based on the principle of ultrasonic "time difference method", which is completely independent research and development, product production has a strict production process, perfect detection means, set a number of patents, to overcome the poor water quality and poor installation environment and many other problems.
Main application areas: new residential district heating billing system, existing building heat metering system, various commercial, facade heating billing system, central air-conditioning billing system.
b.Technical data (continued)
Precision: there are two kinds of precision to choose from: level 2 table and level 3 table
Material: (pipe section: hb59-1, integrator shell: PC)
Nominal size: DN15...DN100
Communication method: it is available in infrared, M_BUS, RS485, GSM, GPRS and other forms
Qn/Qmin = 50
Connection method: pipe thread connection
2. UF2800F series fixed flange ultrasonic heat meter
a.Overview
UF2800F fixed flange ultrasonic heat meter adopts ultrasonic time difference principle to measure the liquid medium flowing through the system to release or absorb heat. The ultrasonic channel is direct type, the water flow channel is straight through unobstructed parts, and the pressure loss is extremely low, which reduces the system's symbol and Operating cost, the product meets the CJ128-2007 standard;
Main application areas: billing of residential heating towers, heating and billing systems for various commercial and school buildings, and central heating and cooling billing systems for large buildings;
b.Technical data (continued)
Nominal size: DN50...DN200
Communication method: it is available in infrared, M_BUS, RS485, GSM, GPRS and other forms
Qn/Qmin = 25
Connection method: fixed flange
