M-211⁄8DIN RATEMETERS, TOTALIZERS, AND BATCH CONTROLLERSFor Voltage and Current InputsThe DPF60 is a combinationmicroprocessor-based digital rateindicator and integrating totalizer.It accepts inputs of 4 to 20 mA,0 to 20 mA, 0 to 5 V, or 1 to 5 V and can be scaled for engineering unitsdirectly from the NEMA 4X (IP66)rated front panel without tweakinginternal potentiometers. The dualstandard 5 A (@ 250 Vac) relays can be assigned to the ratemeter, or tothe totalizer, or one relay to each for batch control and rate alarm.The display features a floatingdecimal point that moves left or right depending on how many “significant figures” the user has selected. In the totalizer mode, 6-digits can bedisplayed. The unit is fully scalable from 0 to 59,999, which indicates the flow rate represented at 20 mA. A peak and valley feature allows the user to call up the recent high and low readings.A square-root extracting input is optional on all units for use with differential pressure flowmeters,such as orifice plates and pitot tubes.With the DPF66, the user can toggle between rate of flow and total flow (6-digits) from the front panel. The rate display is selectable for units per second, minute, or hour,and the totalizer integrates in the same engineering units. The DPF65displays just total flow, while the DPF64 only displays rate of flow.SPECIFICATIONS Accuracy:±0.15% FS for rate and total Temperature Range:Operating:5 to 54°C (41 to 129°F)Storage:-40 to 93°C (-40 to 199°F)Relay Output:2 SPDT relays, 5 A @250 Vac; relays latch or auto-recycle after 0.1 to 99.9 s Power:94 to 126 Vac, 50/60 Hz (or 12 to 24 Vdc) standard; 187 to 253 Vacor 12 to 24 Vdc optional Display: 15 x 8 mm (0.6 x 0.32") LED—6-digits total, 5-digits rate Standby:Non-volatile RAM retains scale settings, presets, output status andtotal flow up to 1 year without power Regulated Power Output: ±5%24 Vdc @ 50 mAOrdering Examples:DPF64-RS232,ratemeter/ batch controller with RS232 output,$289 + 79 = $368.OCW-3, OMEGACARE SM extends standard 2-year warranty to a total of 5 years ($105), $368 + 105 = $473.DPF64-SQRT,digital ratemeter with square root extraction option, $289 + 79 = $368.DPF66 1⁄8DIN, $420, shown actual size.ߜFront-Panel Programmingand Scaling ߜRate and Totalin One Unit ߜRemote orFront-Panel Reset ߜRelays Latch orAuto-RecycleߜZero and Span Adjustable ߜRate Alarm Acts asWindow Alarm with Hysteresis Around Setpoint ߜAnalog Output OptionalDPF60 Series Starts at$OMEGACARE SM extended warranty program is available for models shown on this page.Ask your sales representative for full details when placing an order.

使用手册Instruction manual安徽运诚科技集团有限公司2019.06 版金属管 浮子流量计应运而生因诚而存EMERGE AS THE TIMES REQUIREDEVELOPMENT BASED ON INTEGRITY金属管浮子流量计01概述金属管浮子流量计（金属管转子流量计）是工业自动化过程控制中常用的一种变面积流量测量仪表。
它具有体积小，检测范围大，使用方便等特点，它可用来测量液体、气体以及蒸汽的量，特别适宜低流速小流量的测量。
多年来，金属管浮子流量计以其优良性能和可靠性，以及较好的性能价格比，在石化、钢铁、电力、冶金、轻工、食品、制药、水处理等行业得到了广泛的应用。
本手册面向专业技术人员，适用于金属管浮子流量计的设计选型，也可用于最终用户在使用时的参考。
手册分别介绍了本系列金属管浮子流量计的工作原理、功能特点、技术参数、仪表类型及外形、流量计算、接线方法和安装、维护等。
本手册只针对本系列金属管浮子流量计的设计选型和使用，同时厂家保留某些技术参数改进而不预先通知的权利。
02测量原理本系列金属管浮子流量计主要由两大部分组成：传感器和指示器。
传感主要由连接法兰、测量锥管、浮子和上下导向器组成；指示器主要由壳体、磁传动系统、刻度盘和电远传系统组成。
在垂直的锥形测量管内，有一可上下移动的测量部件——浮子（图1），当流体自下而上通过锥形管时，浮子受到流体的作用力，沿锥形管向 上移动。
当流体的流量增大时，浮子的位移量增大；反之，流体的流量减少时，浮子的位移量变小。
也就是说，流体流量的大小，决定了浮子在测量管中的位置，从而决定了浮子和锥形管之间环形面积的大小。
当流体的流量保持在一个恒定的流量Q时，浮子也处于一动平衡状态，停留在锥形管中的一位置h，此时，浮子和锥形管之间的环形面积保持恒定。
浮子受到三个力的作用：浮子的重力G，浮子受到的浮力F，浮子受到流体的作用力P，这三个力达到平衡。
根据流体动力学的柏努力方程、力平衡原理和流体连续性定律，可以计算出此时通过环形面积的瞬时流体流量，所以，金属管浮子流量计是采用可变面积测量流量的原理。

HJM 型横截面流量计安装使用说明书常州肯诺自动化设备有限公司一、概述随着电厂自动化控制水平的进步，燃煤锅炉的负荷、煤粉量及配风量需要实现在线监测和自动协调控制，使锅炉一、二次配风合理，各风管内风速均匀，就可以保证锅炉燃烧稳定，提高锅炉效率，和经对于生产过程的技术分析济核算等是十分必要的。
但是，迄今为止，存在风速的测量与标定都比较困难，测量的准确度比较底（达不到压力和温度的测量水平），流量计的通用性差等问题。
引起这些问题的原因，主要有以下三个原因：1、流体性质的多样性：压力与温度参数的高低；流体中含尘量的多少；流体粘度的差别；单相流体与多相流体的区别，等等。
这些物性会影响流体状态，在流量测量中必须加以考虑，但又很难精确。
2、管路系统的多样性：管道的直与弯的区别；圆截面与非圆截面的区别；直管段长短不一样，等等。
都会影响流动状态，使流量测量复杂化。
3、流动状态的多样性：由于以上流体的物性和采用管道的不同，会影响到流体的流动状态，诸如旋转流和脉动流；层流、紊流；流动是否达到充分发展，等等。
以上三种影响流量测量的因数，要求我们必须针对被测对象的实际情况选择合适的流量计。
众所周知，由于火力发电厂锅炉二次风管道的直管段极短，或者几乎没有；而且二次风的管道在极有限的距离内，分布有T形管道、L形管道、调节风门、变径管等，使管道内二次风的流动状态变化莫测，这就使得二次风的测量成为非常困难的事情。
在许多场合就不测量了。
在必须测量的场合，不得不采用机翼型测量装置，但这只是一个无奈之举。
因为机翼型测量装置的主要缺点，就是要大大减少二次风的流通面积，一般要减少50%-60%左右。
为了在减少一半以上流通面积的情况下，仍然要保持应有的风量，以维持正常的发电复核的要求，就必须提高风机的功率，增大能源消耗；即使如此，因机翼型结构仍比较长，在一些场合，仍然不能使用机翼型测量装置；即使已安装了机翼型测量装置，因为前后直管道不满足，无法保证测量精度。
