Tennant Ultrasonic BTU流量计说明书

Tennant Ultrasonic BTU流量计说明书

The Series TUF Tennant Ultrasonic BTU Flowmeter is a MID/EN1434 approved highly accurate and stable energy meter. It utilizes ultrasonic technology to measure heating and cooling energy consumption. The Series TUF incorporates a flowmeter, temperature meter, and a calculator into a single, compact unit. The size and lack of moving parts means the Series TUF requires minimal maintenance. The 8-digit LED display enables easy reading of the meter’s recorded values; including temperature, flow-rate, energy consumption, etc. These features make it ideal for installation on chillers, boilers, and individual apartment piping. With the optional couplings it is capable of being used with either NPT or BSPT pipe sizes. It is the perfect meter for tenant billing applications.FEATURES• Lower maintenance costs with local parameter display and no moving parts • Serial communication output allows for easy transfer of data• Flow and temperature monitor in one unit eliminates the need for multiple unitsINSTALLATION NOTES1. Avoid tugging on the temperature probe’s cables.2. Ensure the water is flowing in the direction indicated by the arrow on the meter’s body.3. If several meters are installed on the same vertical pipe work, each meter should be separated from the others to avoid pipe leakage or fallen debris that could affect the other meters’ operation.INSTALLATION INSTRUCTIONS1. Install the meter as shown in either Figure 1 or Figure2.2. Mount the temperature sensor with the blue tag on the corresponding return pipe on application. The sensor with the red tag has already been installed in the meter.3. Flush the system in the proper direction until: • No impurities remain in the filter and pipe.• No water leaks when pressure is added to the system.• The humidity inside the enclosure containing the meter does not exceed 93%.4. After flushing for a period of time; close the ball valves on either side of the meter and flush the impurities out of all filters.*3.6 V ER26500 battery may be purchased separately to power display only.1. Ensure that there is a 10 diameter straight run of pipe upstream and a 5 diameter straight run of pipe downstream form the meter.2. See the installation positions in Figure 3, in which A and B are the proper installation positions, while C and D are the improper positions.3. If the meter is installed on the horizontal pipe, it must be oriented at least 45° fromhorizontal (see Figure 4). If the meter’s face is horizontal, then debris accumulationcan increase inaccuracies (see Figure 5 for correct and incorrect orientations). There is no special requirement when installing on the vertical pipe work.4. Handle display with care. LCD display may damage with force.Note: the meter can be installed on the return pipe or the supply pipe according to user’s needs, but it should be selected in advance.If the following requirements are not followed, then large air particles and impurities in the pipe could influence the meter’s measuring accuracy.Do not install the meter near a high temperature heat source such as during electro gas welding. Doing so after installing an optional battery could cause the battery to explode and causeinjury to people and damage the meter.Do not directly weld the meter on to the pipe; the extreme heat will damage the BTU meter’s internal elements.If not specified at time of order, refer to appendix III to change from supply to return programming.Change from supply to return, and vice-versa, is only possibleusing digital communication protocols.DFigure 2: Installation diagram for TUF-500 to TUF-2000Figure 3: Installation positions Figure 4: Mounting rotation1. If meter is not in use during freezing conditions, drain all water from the connecting pipe. Low temperatures will cause the water to freeze in the pipe and damage the meter.2. This device is intended to be used with clean water. While dirty water will not damage the meter, it will cause errors in the reading.3. A filter should be mounted near the meter and cleaned regularly.4. If the heat exchanging system is operating normally, but the instantaneous flow- rate of the heat meter reduces significantly, then there is too much dirt in the filter. This will narrow the pipe and reduce the flow. Cleaning the filter will fix the problem.5. To protect the meter and avoid damage from harsh conditions, it is recommended that the meter be encased in an enclosure.6. Primary Address: first 2 digits of Manufacturer ID7. Secondary Address: later 8 digits of Manufacturer ID8. Company Code: BAS (08 33)• Version: 541. section.2. Display UnitsEnergy is displayed in kW•h, power is displayed in kW, flow volume is displayed as m 3, and flow-rate is displayed in m 3/h.3. Display Detailsa. “Monthly Reading Date” is displayed as “Pd= XX”, in which XX is the end date of the current month’s energy summation. The factory default value is 31, meaning that the monthly recording period ends at midnight on the 31st day of the month. At this time the current month’s cumulated energy will be stored and the system will begin to record the next month’s energy.b. The meter can store and display the recordings from the past 18 months.c. The units for “Sum of Working Time” (hours) is displayed as h.d. “Software and Protocol Editions” are displayed as “UEr.X.X X.X”. The first X.X is the software edition code and the second X.X is the communication protocol edition code.e. “Leaving-factory serial number” is the meter’s identification number, which is the same as the one in the external label. This serial number is a unique number set by the factory; it is also the secondary address in M-BUS system.f. Battery Voltage displays “UCC=X.XX” (the default unit is Volts). When the battery’s voltage capacity is lower than 2.9±0.1 V, “ ” will appear on the display. This symbol will not appear if no battery is installed.g. If there are any unresolved errors, the start date will display as normal but the end date will display “00-00-00”, and then the error message will be displayed.4. LCD Display Data: • Cooling energy • Heat energy • Volume• Operating time • Flow temperature • Return temperature • Temperature difference • Power• Volume flow • Recorded date • Recorded energy • Recorded volume*Battery not includedCOD=XXXX Low Battery*©Copyright 2021 Dwyer Instruments, Inc.Printed in U.S.A. 1/21FR# 444246-50 Rev. 54.

被测样气中氧含量小于10PPm时,还原性气体的含量应小于1 PPm,被测样气中氧含量大于10PPm时,还原性气体的含量应小于2~4 PPm;请严格遵守以上所列注意事项,否则将造成人为测量误差或重大事故!!!服务与保证仪器自出厂之日起,仪器的保修期限为一年。

二、工作原理仪器的工作原理如图1.0所示。

它主要由气路系统、氧化锆传感器、微机测控系统三部分组成。

2.1气路系统气路系统是用来给氧化锆传感器提供一个稳定流量的纯净样气的系统,样气由进气嘴通入(之前需经过净化处理),经过流量计后,进入传感器(使传感器产生与氧含量相关的电信号),再经过稳流装置后经排气嘴排出。

(压力为负压时需增加气泵增压) 2.2氧化锆传感器氧化锆传感器是由氧化锆陶瓷材料制成的氧浓度差电池,在高温时氧化锆具有氧离子的传导特性,当氧化锆管的两个电极之间的氧分压不同时,氧浓度差电池产生一个与氧浓度成比例的电势,电势大小按下式计算:E = lnRT 4FP 0 P式中:R ——理想气体常数F ——法拉第常数T ——氧化锆加热炉绝对温度(K)P0 ——空气中氧分压(20.6%)P ——样气中的氧分压通过测量氧浓度差电池的电动势E与温度T,就可以计算出样气中的氧分压,即氧含量。

浓度差电池的各种干扰电势,如本底电势、渗透效应、气流冷却效应等,通过硬件和软件的特殊设计进行修正。

2.3微机测控系统微机测控系统以单片机为核心,外围信号变换及放大电路、模拟开关、温控电路、显示器、PID控制调节输出、标准电流、电压输出,过温保护电路等组成,用来对测试结果进行计算、修正、控制和信号输出。

四、仪器的面板结构仪器的前、后面板分别如图1.1、图1.2所示。

前面板电源开关和流量计组成;流量计可以根据实际需要调节流过传感器的样气流量;后面板自左向右依次由排气口、(I、II、III三路)进气口、排风扇、RS-485、电流和控制输出接线端子和交流电源插座组成。

RS-485通过485转USB输出端子连接至PC机;后排接线端子输出的信号,可以远传至控制室或控制其他设备的动作;排风扇则可以为整机起到降温的效果。

图1.1 仪器的前面板图1.2 仪器的后面板五、仪器的安装5.1仪器安装前的检查仪器由运输或存放状态转入使用前,应做如下检查:(1)附件及外观检查检查电源电缆、通讯电缆、安装软件、使用说明书、等附件是否齐全及完好;仪器外观不应该有划伤、变形现象,无异常现象后方可通电检查。

(2)仪器通电后的检查首先将安装软件装入电脑,接入数据通讯线,仪器通电后,打开O2 Controlor软件,设置好通讯端口,软件下方temperature:窗口的温度应不断增加,当数字增加到750温定后,仪器方可正常测量。

接入24V气泵控制电源,能听到气泵轻微的嗡嗡声。

用流量调节阀可使流量在零到最大范围内任意调节。

符合以上现象后方可继续下面的安装和使用。

如果仪器有缺损或通电后显示异常请不要使用,应立即与我公司售后服务部联系,以便妥善处理,避免仪器严重损坏或事故发生!5.2仪器的安装仪器的安装必须按下述要求进行,否则将无法保证仪器正常使用。

5.2.1电源的连接仪器使用220VAC±10%、50HZ/60HZ,3A电源,要求接地良好,不应有高频或强磁场干扰。

建议用户给仪器配备有净化功能的交流稳压器或UPS 电源,以确保仪器在长期的使用中有稳定的电源供给。

5.2.2通讯电缆的连接本仪器提供串行异步半双工RS485 通讯接口,采用MODBUS-RTU 协议,通讯线缆经过485转USB直接与PC相连。

USB的一端直接插入电脑,另一端与仪器后面板DB9针连接。

5.2.3 通讯USB-485驱动的安装打开仪器提供的光盘,找到UT850文件夹,根据所使用的操作系统选择相应的驱动,如以XP为例选择,运行程序,进行驱动的安装,安装完成后插入USB-485设备,进入电脑设备管理器端口(COM和LPT)项,记录此时的串口端口,此处为COM2(不同电脑此项端口号不同)5.2.4软件操作5.2.4.1运行软件主界面区由三部分组成:菜单设置区、实时数据显示区、历史数据设置和数据曲线记录区。

⏹菜单设置区:◆Language语言选择:可实现软件的中英文切换;◆Option功能设置:可进行仪器各项参数的设置;◆About关于软件;主要说明一下Option功能设置项:点击Option出现四级设置菜单:A、Comm Setting:通讯端口设置菜单设置Port:USB通讯端口设置项:选择端口号,参照5.2.3;Bauding:波特率设置:设置为9600;DataBit:数据位数:设置为8位;StopBit:停止位:设置为1位;Parity:奇偶检验位:设置为无校验;打开仪器电源,然后进行以上端口设置,点击Connect按钮,进行仪器通讯连接。

连接后软件左下角出现标志,代表连接成功,反之显示连接失败。

B、PID Parameter:PID参数设置项单击PID Parameter项出现密码对话框输入密码:输入“2222”后进入PID 设置项。

O2 Setpoint:需要设定的目标氧含量;Offset:相对于目标氧含量进行的正负偏移量调节;PID P Parm(P):比例控制。

输出与输入误差信号成比例关系,比例控制能迅速反应误差,从而减小稳态误差。

PID I Parm(I): 控制器的输出与输入误差信号的积分成正比关系。

积分项对误差取决于时间的积分,随着时间的增加,积分项会增大。

这样,即便误差很小,积分项也会随着时间的增加而加大,它推动控制器的输出增大使稳态误差进一步减小,直到等于零。

因此,比例+积分(PI)控制器,可以使系统在进入稳态后无稳态误差。

PID D Parm(D):控制器的输出与输入误差信号的微分(即误差的变化率)成正比关系。

它能预测误差变化的趋势,这样,具有比例+微分的控制器,就能够提前使抑制误差的控制作用等于零,甚至为负值,从而避免了被控量的严重超调。
