Ultrasonic thermal energy meter is an instrument used to measure and display the heat released or absorbed by waterflowing through the heat exchange system.This product has the characteristics of beautiful appearance,convenientinstallation,accurate measurement,stable operation,strong anti-fouling and anti-corrosion ability,long service life,safety and reliability,economical and practical,etc.It can be widely used in central heating and household meteringheating facilities.The product complies with the CJ128-2007 industry standard and the detection is based on theerification procedure JJG 225-2001.
.The flow sensor of this meter measures accurately,is not affected by rust in the water and external magnetic fieldinterference,and is suitable for heating water.The shell is processed by hard die forging,CNC machine tools and assemblymachine tools,with good mechanical strength and high dimensional accuracy;
.The temperature sensor adopts PT1000 platinum resistance paired temperature sensor,equipped with high-precisionAD circuit to achieve high-precision temperature measurement;
.Ultra-low power consumption microprocessor,powerful function,low power consumption,strong anti-electromagnetic interference ability;
.It has self-diagnosis,fault display and power-off data protection functions.When the heat meter fails accidentally,thefault code is displayed and the current data is automatically saved;
.Equipped with LCD display,the data display is complete and accurate,the data reading is convenient and fast,and thereal-time clock design displays the date and record;
.Adopt environmentally friendly batteries,the battery life is more than 6 years;
.The body structure is beautiful in appearance,the display can be rotated horizontally and flipped vertically,thereading is convenient,the single-button design is easy to operate,the display screen rotates 360 degrees horizontally and180 degrees vertically,which is easy to install;
.Adopting the GP21 metering chip produced by ACAM of Germany,the data is accurate and stable;
.Complete interfaces,expandable RS-485 bus,M-bus,LoRa wireless,NB-loT wireless,to achieve remote data collection and centralized control;
.Easy to install and maintain,with dustproof,moisture-proof,waterproof,anti-disassembly,anti-vandalism and otherfunctions.
