现场可调,BACnet/Modbus输出
IEFB是一种现场可调插入式热能计,使用电磁技术精确可靠地测量流体速度和能量消耗。高精度IEFB可调,以适应4至10”(100至250 mm)的管道尺寸,而标准精度IEFB适用于4至36”(100至900 mm)的管道尺寸。IEFB将一个温度计和一个计算器集成到一个单元中。液晶显示屏提供仪表值的清晰读数,包括温度和能耗,因此非常适合安装在冷水机组、锅炉和其他加热和制冷应用中。测量精度高,寿命长,年运行成本*低。此外,它还提供多种输出选项,包括2线RS-485上可选择的BACnet MS/TP或ModbusRTU通信协议和标准模拟、频率和报警输出。
产品应用
监控冷水机冷却输出性能工业锅炉加热性能能效监控热能优化性能商业和住宅热能消耗和计量区域供热和制冷监控能源成本分配监控功能灵活,现场可配置设置显示(-LCD集成选件或远程附件A-IEF-DSP)可适应多种应用配置。应用信息可选择显示,包括管道尺寸、管道材料、液体类型、模拟输出、脉冲/频率输出、警报输出、通信、输出、阻尼和校准系数 通过温度变化保持高性能精度,密度和/或粘度 安装向导和安装工具易于使用,提供快速和精确的安装
附件安装套件A-IEF-kit配有测厚仪和卷尺,以确保准确的安装深度 流量计没有可防止结垢的移动部件和电极,这使流量计具有较长的使用寿命*大限度地减少维护的需要热取压隔离阀配件允许在操作系统中轻松安装和拆卸,而无需系统停机
