General
1.1 Introduction
FMC-5000 Series Coriolis Mass Flowmeter (here after FMC Coriolis Meter) is designed according
to the Coriolis Force Principle. It is widely used for the process detecting and custody transfer/fiscal
unit in many industries such as petroleum, petro-chemical, chemical industry, pharmacy, paper
making, food, energy, and so on. As an advanced flow and density measurement instrument, it is
widely used in the measurement of Liquids, Gas and Slurries.
1.2 Principle
FMC Coriolis Meter is designed according to the principle of Coriolis force. Under the alternating
current effect, the electromagnetic coils mounted on the measuring tube will make two parallel
measuring tubes vibrating at a certain fixed frequency. Whenever mass (either liquid or air) flows
through the measuring tubes, Coriolis force is generated, causing a “bending” or “deflection” in the
top of the tubes. This deflection is sensed as a phase shift between two electronic pick-ups mounted
on the tubes. The degree of phase shift is directly proportional to the mass flow within the tubes.
The mass flow rate can be calculated by detecting the phase shift of the tubes.
The vibration frequency of measuring tube is determined by the total mass of measuring tube and
inner mass flow. The vibration frequency of measuring tube changes over the changes of mass
flow density. Thus, the flow density can be calculated.
Working together with the measuring circuit, the temperature sensor mounted on the measuring
tubes can obtain the real-time temperature value.
5 / 36
1.3 Features
Compared to traditional flow measurement methods, FMC Coriolis Meters have the following
obvious advantages:
1.3.1 Ability to directly measure the mass flow rate in the measuring tubes without any
conversions, which avoids intermediate measurement errors. The mass flow is measured with high
accuracy, good repeatability and a wide turndown ratio.
1.3.2 A wide range of flows, such as the steady uniform flows of common viscosity fluids, high
viscosity fluids, non-Newtonian fluid, slurries containing solid components and liquids containing a
little air.
1.3.3 With little vibration, the measuring tube can be regarded as no-moving parts, which will
reduce the meter maintenance, and ensure the stability and long life.
1.3.4 Besides the mass flow measurement, density, temperature and even consistency can also
be measured and output.

Table 6: Flow rate factor for calculating medium speed
In many cases, we need to know the flow rate of the medium while using the FMC Coriolis Meter
for Air measurement. Connection size reducing is common for mass flow meter Air measurement
applications, thus the flow rate of the FMC Coriolis Meter needs to be checked according to the
formula below:

Note:
 The Gaseous medium flow velocity is usually much higher than liquid when measured by a
flow meter, so there will be noise caused by gas medium and tube wall of flow meter under
high speed gas flow and if the noise become large enough, the signal of flow meter will be
influenced, so please use FMC Coriolis Meter for gaseous medium measurement
at speed less than 1/3 Mach (110m/s)!
 Please use FMC Coriolis Meters for Gas with a
pressure drop no more than 0.2Mpa!

Installation
3.1 Brief
3.1.1 Pre-installation
This section offers instructions for installation, wiring, operation, and trouble-shooting. The user
must read this manual carefully before installation and operation, because improper installation
may cause incorrect measurement and even damage the flow meter.
3.1.2 Safety
When the flow meter is going to be installed in the dangerous area, please confirm that the
flow meter’s explosion-proof class is consistent with the environmental requirements in
order to avoid the potential danger.
Make sure that the power is shut off to avoid electric shock when installing the transmitter.
Follow the installation and operation instructions to ensure the safe operation.
3.1.3 Components
FMC Coriolis Meter is made up of a sensor (measuring tubes) and a transmitter, which can be
installed integrally or separately. When FMC Coriolis Meter is installed separately, the sensor and
transmitter should be connected by special Nine-Core Cable.
3.2 Installation
3.2.1 Installation Process

Step 1: Location: Determine the sensor installation location, which should take the installation
area, pipeline, transmitter location and valves into account.

Step 2: Direction: Determine the sensor installation direction in the pipeline.

Step 3: Installation: Install the sensor and transmitter in the pipeline.

Step 4: Connection: When FMC Coriolis Meter is installed separately; the sensor and
transmitter should be connected by special Nine-Core Cable.

Step 5: Start-up.
3.2.2 Position selection

The sensor should be placed away from interference sources (such as a pump) which may
cause pipe mechanical vibration. If sensors are used in series along the same line, care must
15 / 36
be taken to avoid the mutual influence due to vibration resonance. The distance between
sensors should be no less than 2 meters.

When installing the sensor, pay attention to the expansion and contraction of the process
pipeline due to temperature changes. It is strongly recommended that the sensor not be
installed near an expansion joint of the process pipeline. Otherwise, the pipe expansion and
contraction of the pipeline will bring about transverse stress which will affect the sensor‘s zero
which will affect the measurement accuracy.

The sensor should be placed at least 5M away from industrial electromagnetic interference
sources such as large power motors and transformers.

The sensor should be placed in the position where its measuring tube is always filled with fluids
and a certain pressure at the outlet is maintained, thus it should be placed in a lower position
of the pipeline.

Basic requirement: Install the FMC Coriolis Meter in a lower position of the pipeline so that the
fluid can fill the sensor during the process of zero-point calibration and operation. The
transmitter should be installed in the environment with temperature from -40~+55 ℃ and
humidity <90%.

Dangerous area: Please confirm the explosion-proof class indicated in the nameplate of FMC
Coriolis Meter matches the application environment regulation before installation.

Straight pipe: The FMC Coriolis Meter does not require the special straight pipe upstream or
downstream. However, if more than one mass flow transmitters are installed in the same pipe,
please ensure the length of pipe between any two sets is more than 2 meters.

3.2.5 Valve
It is necessary to conduct the zero-point calibration once the installation is completed. The
downstream stop valve must be closed before zero-point calibration, and then close the upstream
stop valve.
3.3 Direction
3.3.1Basic requirement:
The FMC Coriolis Meter should be installed in the orientation that can ensure the measuring tube
is filled with the medium being measured.
For horizontal installation, the measuring tube should be installed under the pipe when the process
medium is liquid or slurry (shown on Drawing 9) and on top of the pipe when the process medium
is gas (shown on Drawing 10). For vertical installation, the measuring tube would be installed
besides the pipe when the process medium is liquid, slurry or gas (shown on Drawing 11)
Drawing 9
Drawing 10
17 / 36
Drawing 11
3.3.2 Flow direction:
There is flow direction arrow that indicates the proper flow direction on the front of the sensor,
install the FMC Coriolis Meter accordingly.
For vertical installation, if the process medium is liquid or slurry, the flow direction should be from
down-to-up; if the process medium is gas, the flow direction can be either down-to-up or up-todown. The transmitter can be mounted with 90° rotation according to the requirement of installation.
3.4 Sensor Installation
3.4.1 Basic requirements:
The installation of the FMC Coriolis Meter should be in a straight line.
Meanwhile, do not support the pipeline with FMC Coriolis Meter. (As
shown in Drawing 12)
3.4.2 Installation of the FMC Coriolis Meter 6” or lager:
It is better to support the sensor of FMC Coriolis Meter using rubber
connectors as the buffer.
3.5 Wiring
3.5.1 Basic requirements:
If the sensor of FMC Coriolis Meter is installed integrally with the transmitter, it will be OK that the
power of transmitter is connected. If the sensor of FMC Coriolis Meter is installed separately from
the transmitter, it will be required that the transmitter is connected with sensor through special ninecore cable. If the FMC Coriolis Meter 6” (DN150mm) or larger is installed, it is required that the
drive-amplifier of sensor is supplied with separate power.
3.5.2 Junction box
If the sensor and the transmitter are installed separately, the sensor and transmitter have been
respectively matched with junction box for connecting the special nine-core cable.
3.5.3 Cable connection
If the sensor and the transmitter are installed separately, signal lines are 9-core cables between
transmitters and mass flow sensors.

Temperature Compensation
Cut off power before connecting cables. The power voltage must match that
indicated in the junction box of the transmitter and the ground wire must be well
grounded to ensure its intrinsic safety performance.
19 / 36
3.5.4
Grounding
Both of the sensor and the transmitter have to be grounded correctly, otherwise a measurement
error will occur and the FMC Coriolis Meter may not work. If the pipeline is grounded, the transmitter
can be grounded through the pipeline; if the pipeline is not grounded, the transmitter should be
grounded independently.
3.5.5 Power line wiring
The transmitter can be supplied with 18-36V dc (Standard) or 85-265V ac (Optional). The power
line more than 0.8mm2 is recommended and the maximum length of power line should be 300m.
For FMC Coriolis Meter 6” or larger, a separate driver amplifier is required to be supplied for power.
3.6 Start-up
3.6.1 Zero-point calibration
Zero-point calibration supplies the base point for the flow meter. After the first installation or
reinstallation, Zero-point calibration is required for the FMC Coriolis Meter. Before zero-point
calibration, close the valve downstream of the flow sensor to make sure that no fluid is flowing
through the pipe. The sensor should be filled with process fluid whose temperature change should
not exceed ±10℃. If the flow meter is zeroed when fluids are flowing through, its measurement will
appear much smaller. At that time, stop using the meter or re-zero it before use.
3.6.2 Instrument coefficient
Each FMC Coriolis Meter has its own instrument coefficients, which has been set before delivery
and shown on the calibration report. So the user does not need to set instrument coefficients except
if either the sensor or the transmitter is replaced. All the coefficients that can be found on the
calibration report are also printed on the name plate. Generally, the sensor and the transmitter are
coupled, and the coefficient has been input into the transmitter. The meter can be used without
additional change.

5.3 Calibration
Generally speaking, the FMC Coriolis Meter does not need field calibration because it has been
calibrated before delivery.
Each FMC Coriolis Meter has its own instrumental coefficient, including one flow coefficient and
four density coefficients (high density D1, high period K1, low density D2 and low period K2), which
will be shown in Nameplate of Sensor or Calibration certificate.
The sensor and transmitter are usually delivered as a pair and instrumental coefficient has been
set in the transmitter so the user does not need to change.
5.3.1 Zero Calibration
Zero calibration provides the reference point for the flow meter. It is necessary to conduct the zero
calibration whenever the FMC Coriolis Meter installation is performed.
After installation, the FMC Coriolis Meter should be powered at least 30 minutes for warm-up
and then pass flow through the flow meter until the temperature of FMC Coriolis Meter is
same as working temperature of fluid. Afterward, close the downstream valve, make the fluid
pass through the flow meter under normal temperature, density and pressure and then close the
upstream valve to assure the sensor is full of liquid during the process of zero calibration.
Notice: Each zero calibration lasts 30s and must repeat at least 10 times.

5.3.2 Flow Calibration
The mass measured by the FMC Coriolis Meter is resulted from the multiplication of detected
signals’ time difference between two circuits and flow calibration factor. If the accuracy is not up to
grade after long-term service, please modify the flow calibration factor according to the following
formula:
K1=K0× [1+ (M-Mt) / Mt] =K0×M/Mt
Note:
K1
New flow calibration factor,
K0
Old flow calibration factor,
M
Total mass flow of Master Meter,
Mt
Total mass flow of Tested Meter.

Pressure Loss
The pressure loss of FMC Coriolis Meter can be checked on the following Pressure Loss Charts
(including pressure loss, flow, and viscosity parameters).
When the viscosity is between two adjacent pressure loss lines, the pressure loss can be calculated
with following formula:
Note:

The mass flow value can be converted to the volume flow value with followed formula:
Volume flow rate = Mass flow rate / Density
Follow is the pressure loss for different size flow meter

Trouble Shooting
7.1 Overview
Upon first installation and operation, if there is an abnormal working phenomenon, the user should
determine the causes.
Generally speaking, the causes may one of two kinds: flow meter or application causes. Application
problems are usually complex. Fluctuation measurement error caused by the process or medium
status changes, should be analyzed according to the actual application. This chapter mainly
focuses on the causes and troubleshooting of flow meter system malfunctions.
7.2 Diagnostic Tool
For flow meter fault diagnosis, the user can check the OLED indicator and LCD displays, OLED
lights of different colors and brightness contrast on the panel, which represent the working condition
of flow meter. Meanwhile, LCD displays can show the self-diagnostic alarm information of the
transmitter, which is useful for defining the malfunctions.
In addition, it is necessary to use handheld digital multi-meter when testing the static resistance
values and cables of the sensor.
The proportion of light and dark shown by OLED indicator represents the working condition of the
flow meter.

Initial installation of electricity power should be checked to ensure the following:
Choose the correct voltage for power supply, connect the power cable correctly, open insulating
layer of two ends of the cable and connect them firmly;
AC Power cable should not be connected through the same output as the signal cables;
Transmitter should be grounded firmly and the earth resistance should be less than 1 Ω, (use the
copper wire 10 gauge minimum).
