2 SYSTEM DESCRIPTION 系统描述
2.1 SYSTEM DESCRIPTION 系统概述
ViscoSense®2 is, besides other applications, intended for use in fuel oil treatment systems to obtain
a correct measurement and control of the fuel oil viscosity.
扭转振动黏度计ViscoSense®2 既是应用于燃油处理系统以期对燃油的粘度进行准确测量及调控
Figure 1 shows a typical fuel treatment system with return line from the engine. In this system, the
degassing/mixing tank operates as a fuel buffer, ensuring gradual changes of viscosity which results
in a stable control of the viscosity. The ViscoSense®2 sensor is used to measure the actual viscosity
of the fuel oil. The signal from the sensor is compared to the setpoint of a viscosity controller, which
regulates the output of the fuel heater via a control element (steam or thermal oil valve, or electric
heater cabinet).
Figure 1 Typical example of an automatic control system using steam or thermal oil heater

2.3 PRINCIPLE OF OPERATION 操作原理
The patented measuring principle is based on rotational vibration of a pendulum in liquid.
已获得专利权的测量原理系以传感器探头在流体中的旋转振动为基础
The sensor consists of a sensor head (1) attached to a base plate (2) by a torsion tube (3). Two sets
of piezo-electric elements (4) are positioned inside the pendulum. One set drives the pendulum, the
other set measures and controls the rotational movement of the pendulum via a feedback circuit. In
this way the pendulum is kept in vibration at its resonance frequency.
传感器系由通过扭管(3)固定在基座(2)上的钟摆(1)组成。钟摆内置两套压电陶瓷元件(4)。一套驱动钟
摆，而另一套通过反馈信号测量和控制钟摆的旋转动作。这样使钟摆在其共振频率上保持振动。
Measuring the resulting frequency at two specific values of phase difference, yields a value for the
damping which is proportional to the square root of the dynamic viscosity.
测量相位差两点的频率，得出衰减值。这一数值与动力黏度的平方根成正比。
A flow tube (5) is placed around the pendulum, to protect it against mechanical damage.
流管(5)被置于钟摆外围，以保护钟摆避免机械损坏。
The flowtube is machined with a smooth surface, as well as with a triplet of oval slits. These slits
increase the refreshing rate between sensor and flowtube.
流管经过精细机加工处理，表面光滑并有三个椭圆形开口。这些开口增加了传感器探头和流管之间的
更新速率。

6.2 CONDITIONS FOR CORRECT WORKING OF THE VISCOSENSE®2 SENSOR 传感器
正确工作的基本要素
The flow should be in-between the maximum and minimum fluid flow rate as mentioned in chapter
21.1
流速应当在第21.1章介绍的最小值与最大值之间
The ViscoSense®2 housing should be placed in such a way, that no air can be trapped in the
housing. This can easily happen if the inner diameter of the piping is smaller than the inner diameter
of the ViscoSense®2 housing, if it has been installed horizontally. 探头安放室应当放置合理以至于没
有空气可能进入滯留室内。当管路内经小于安放室内经，并水平安装时，这一点很容易發生。
If the inner diameter of the piping is smaller than the inner diameter of the ViscoSense®2 housing, the
transitions between the two diameters should be tapered.
The inner diameter of the ViscoSense® housing should not be smaller than the piping.
如果管路內径小於粘度傳感器探头安放室的內径，應當使用管道变径转换接头。传感器舱室内径不能小
于管道内径。
The fluid should be homogenous. 流体应当保持均质
It should not contain any air bubbles or foam. 流体中不应含有任何气泡或泡沫。
THE FLUID SHOULD NOT CONTAIN ANY CHEMICALS OR SOLID PARTICLES
THAT CAN DAMAGE TEFLON®
流体当中不应含有任何其它化学物及固体颗粒，以防止损坏特富龙®涂层。
THE FUEL SHOULD BE IN COMPLIANCE WITH ISO 8217:2010
(SPECIFICATIONS OF MARINE FUELS).
燃油应当符合ISO 8217:2010
（船用燃料标准规范）。

6.3 GENERAL INSTALLATION RECOMMENDATIONS 一般安装建议
Mount the ViscoSense®2 housing as low as possible, in the fuel system. 尽可能低地安放
探头仓室
Compare your process variables with the specifications. Make sure these are compatible!
对照技术规格说明书比较工艺变量，确保其是可兼容的！
Pressure pulsations and variations should be avoided as much as possible.
尽可能地避免压力波动和变化。
Mechanical vibrations should be avoided as much as possible. 尽可能避免机械振动。
No special tools are required to install the ViscoSense®2. Ensure that your standard tools
are fit for the job. 安装传感器无需特殊工具。只需确保标准工具正常即可。
Make sure that the working environment is clean. Ensure that no dirt can enter the
sensor. 确保工作环境清洁，无灰尘进入探头。
Insulate the pipes and the sensor housing well, to avoid any temperature loss of the fluid.
管路及传感器舱室应良好绝缘，防止温度损失。
When fuel viscosity is 500 mPa·s or thicker it is recommended to wrap steam tracing with
sufficient capacity, or 20 Watts/metre resistance wiring around the ViscoSense®2
housing.
当燃油黏度等于或大于500毫米帕斯卡·秒时，建议充分包裹蒸汽源及传感器仓室
VAF ViscoSense®2 sensor and interface box are precision instruments. Handle them with
care. VAF扭转振动传感器及界面盒属精密仪器，应小心轻放！
Do not unscrew the cable gland on the top of the ViscoSense
®
2 sensor or disconnect the
cable from the sensor. This will violate the correct operation of the ViscoSense®2 sensor.
勿拧开探头顶端电缆或从探头断开电缆。这将严重违反正确的操作规程。
Take care that the pendulum is not damaged and the torsion tube not bent by
mechanical force. This will violate the ViscoSense®2 signal.
小心轻放，特别注意钟摆和扭管免受损伤以及机械力而弯曲。否则，这会影响传感器信
号。

16
6.4 MECHANICAL INSTALLATION 机械安装
6.4.1 ViscoSense®2 interface box 传感器界面盒
1. Install the ViscoSense®2 interface box in a suitable location, free from excessive vibrations,
humidity and excessive temperature variations. 界面盒应安放在适合的地方，避免过渡振动以及
温湿度变化。
2. The maximum distance between sensor and the interface box is determined by the cable length
from the sensor, being approx. 5 metres. 传感器与界面盒之间的距离是由传感器电缆长度决定
的，大约5米。
3. Allow sufficient space for installation of cables and for servicing. 留有充分空间以便安装电缆和服
务需要。
6.4.2 ViscoSense®2 housing 传感器安放室
1. Remove dust caps from sensor housing and install housing stress-free, with shutoff valves and
bypass valve in the fuel piping as illustrated in Figure 6. Take care that the flow direction is in
accordance with the indication on the housing (inlet, outlet and arrow) as illustrated in figure 8.
Support inlet and outlet piping sufficiently. 除去防尘盖，根据图6所示，安装仓室，止阀及辅助阀
门。按图8所示，根据仓室表面指示，注意流动方向(入口，出口及箭头)，充分固定入出口管路。
These shutoff valves and bypass valve are not furnished by VAF Instruments.
这里的止阀及旁通阀非VAF提供。
2. Note that the distance between fuel heater and sensor housing inlet should not exceed 4 metres.
注意：燃油加热器与探头安放仓室入口间的距离不应超过4米。
3. To protect the instrument from excessive vibrations, which can cause malfunctioning of the
instrument, it is recommended to: 为防止仪器因过渡振动引起的误操作，建议：
Install the ViscoSense®2as low as possible in the fuel system close to a solid structure or
beam.
在燃油系统中尽可能低的安装传感器，并靠近稳固结构或梁。
Install suitable pipe clamps at both sides of the ViscoSense®2 sensor.
在传感器两侧安装适当的管夹。
4. Allow at least 50 cm clearance to the sensor housing, to be able to take out the measuring sensor
for service.
预留至少50公分距离，以便于维修服务时取出探头。

17
5. The sensor needs a stable environment to act as a counterweight for the pendulum movement.
The support must prevent movement and excessive vibrations of the ViscoSense®2 housing,
especially movement in the direction of the pendulum movement (see drawing- angular
movement around the sensor axis). Therefore there must be two supports to the inlet and outlet
perpendicular to the pipe and perpendicular to the ViscoSense®2. If one support would be used
the lateral vibrations would be converted to angular vibrations and the situation would be made
worse instead of better.
传感器需要一个稳定的工作环境，以保持钟摆运动的平衡。支撑固定架必须起到防止探头仓室移动
及过渡振动的作用，尤其是防止其在钟摆运动方向上运动(参看图纸-钟摆环绕传感器轴线的角度 运
动)。因此必须有两个固定支撑架，分别位于入口和出口，且与管路及传感器垂直。若仅使用一个
支撑，那么横向振动既会转换为角振动，系统情况将变得异常糟糕。

18
Figure 6 Sensor installation diagram
图 6 探头安装图示
The angular position of the supports must always be 90° in relation to the sensor.
固定架与探头之间的角度必须90º。
The distance from the flange to the support should be two times the diameter of the pipe.
法兰与固定架之间的距离应为管路直径的两倍。

6.4.3 To assemble ViscoSense®2 sensor 如何安装传感器
1. Check the O-ring for damage, before installing the ViscoSense®2 sensor. Replace if necessary.
Make sure only one original o-ring is installed. 安装前查看密封圈是否受损，必要时进行更换。确保
只安装一个原装的密封圈。
2. Remove transport locking cap from bottom side of flowtube. 从流管底部拆除运输中防止残损的锁
定鞘
3. Please make sure not to damage the Teflon®coating during installation. 安装中杜绝损伤特氟龙
涂层。
Without the transport locking cap the sensor is not protected against excessive
mechanical shocks which can occur during handling.
注意： 没有锁定鞘，既无法保证探头在运输，装卸过程中可能受到的过度的机械振动
冲击影响。
4. Install sensor carefully in housing with the closed surface facing the flow, illustrated in figure 8.
小心地将探头置于安放仓室内，注意流管的封闭面朝向流动方向，参见图8 。
Make sure the flow tube closed surface is pointing towards the inlet of the sensor
housing, see figure 8. The sensor will not work correctly if installed wrongly.
确保流管封闭面朝向探头安放仓室入口。不正确的安装会导致传感器无法正常工作。
Check if the position of the hole inside the housing and the fixation pin on the
sensor match. 检查探头上用于固定的插头与安放室内的孔眼是否对位。
5. Tighten the nut (1) by hand. If there is a temperature difference between the sensor and the
housing you should wait until they have the same temperature before tightening the nut.
首先用手固定螺帽(1) 。在紧固前若探头与仓室间有温差，则应等待直到两者温度相同为止。
6. Tighten the nut (1) with a wrench with a recommended torque of 100 Nm.
然后用螺旋钳在100牛顿米的扭转力矩下上紧螺帽(1)
Make sure that all flange bolts and nuts are tightened correctly before re-pressurizing the
