SENSOSTAR®2BU声波(冷)热量表SENSOSTAR®2BUUltrasonic Heat-Cool Meter
产品综述Product Description
它包含一个声波流量计测量供水或回水流量， 一对机带温度传感器分别测量供回水温度，和一个能够将流量及温差换算成（冷）热量的积分仪。热水所提供的热量或冷水所提供的冷量与水流量及供回水温差成比例关系。
SENSOSTAR®2BUcontains an ultrasonic flowmeter for flow measurement in supply or return pipe, a pair of temperature sensors for temperature measurement in supply and return water, and a calculator which integrates flow and temperature difference into energy consumption.
流量计采用声波测量原理，内部无可动部件，无磨损。量程比1:1000，合EN1434的1:100的要求。
The flowmeter employs ultrasonic principle, there is no moving part and thus no wearing. Its dynamic range of 1:1000 fulfills the requirem ents by EN1434 which is 1:100.
供回水温度通过铂电阻温度计PT500测量，具有快捷智能的自适应温度测量间隔。在变化的系统条件下(例如流量瞬时),SENSOSTAR®2BU可以在时间内快速测量温度变化间隔，调整以适应条件变化，“精准测量”。
The temperatures in supply and return water are measured with PT500. Its fast, intelligent and adaptive temperature measuring intervals improve the accuracy and response.
积分仪将流量和供回水温差的乘积进行积分运算处理，后得出所消耗的热量。
The calculator integrates the temperature difference between supply and return water and flow and deliver the energy consumption.
宽大清晰的信息显示便于读数，按键和合EN 62056-21的光电接口便于现场操作。
Easy reading due to big and clear LCD display, push-button and optical interface conforming with EN 62056-21 simplify field operation.
M-Bus远程通讯便于系统集成。
M-Bus communication is suitable for system integration.
自诊断功能使得维护变得简单。
Self diagnostics make the maintenance easy.
SENSOSTAR®2BU可以水平、垂直、倒置等任意方向安装。
SENSOSTAR®2BUcan be mounted in any orientation: horizontal, vertical or overhead.
电子单元可拆卸，便于一体或分体安装。
Detachable electronics make the compact or remote mounting possible.
电池使用寿命长达11年，可选其他电池。
Battery of several options, service as long as e.g. 11 years.
流向标志
Activity indicator at flow
星号:校准值
Star syol: calibrated value
上一年数值标志
Icon for previous year value
上一个月数值标志
Icon for previous month value
值标志Icon for maximum
箭头标志将显示上一年或上一月的存储值。校准值(例如能量)通过星号表示。小数点后面的几位用边框框起。
The arrow icons mark the display of a stored value of the previous year or previous month. A calibrated value (e.g. energy) is marked on the display via a star syol. The dis after the decimal point are indicated by a surrounding frame.
热量表的显示也分为不同的层级。„短按“(< 2秒.)当前层级逐行显示， 后一行显示完毕，行重新显示。„长按“(> 3秒.)下一层级的行将开始显示。后一层显示完毕，层重新显示。
The display is grouped into several loops. By a „short press“(< 2 sec.) the current loop is ped through line by line. After the last line the first line is repeated again. By a „long press“(> 3 sec.) the first line of the next loop is displayed. After the last loop the first is repeated again.
