Chapter 1. Measuring configuration system and model MTG structure Outline of this chapter This chapter presents the equipment configuration of a measuring system using this instrument. It also describes the structure and the names and functions of various parts of the main unit.
Page 10: System Configuration
1-1. System configuration Measuring system Introduction This instrument is a two-wire electromagnetic flowmeter operated on 4-20mA DC. It measures the flow rate of conductive fluid flowing in the detector and outputs a signal that is suitable for the measuring range. Concept of flow rate measurement by this instrument The concept of a flow rate measuring system using this instrument is shown.
Page 11 System configuration 1 for analog output System configuration An example of system configuration is shown. The instantaneous flow rate values measured by this instrument are outputted as a 4-20mA DC analog signal. In this system configuration, the analog signal from the instrument can be outputted directly to a host control system.
Page 12 System configuration for digital output (DE output) System configuration In the system configuration shown below, the flow rate measurements, database and self- diagnosis results of this instrument are outputted on the DE (digital enhancement) protocol, which is a communication protocol for digital signals. In this system configuration, the instrument transmits digital signals on the DE protocol and the smart protocol converter (SPC) converts the digital signals into analog signals, which is outputted to a control system.
Page 13 System configuration for pulse output System configuration An example of system configuration is shown. Instantaneous flow rate values measured by this instrument are outputted as a pulse output with the specified pulse width and pulse weight. Besides an analog signal, this system configuration allows the instrument to output a pulse output to an electronic counter, sequencer or other host control system or counter.
Page 14 System configuration for contact output System configuration An example of system configuration is shown. If the instantaneous flow rate value measured by this instrument reaches to the upper or lower limit settings or a major failure occurs in the instrument, that state is outputted as a contact output. In this system configuration, it is not only an analog signal but also the instrument to output the contact output to a sequencer or other host control system.

Page 83: Changing Setting Of Damping Time Constant
5-5-1. Changing setting of damping time constant Damping means a response time of the primary time lag (63.2% response) for a step response of the flow rate. If the out fluctuations are large, increase the damping. A large damping value stabilizes the output but lowers the response performance.
Page 84: Auto Zero Adjustment
5-5-2. Auto zero adjustment Auto zero must be carried out only under the condition when the detector is filled with process fluid at zero flow. Run this function only after installing the electromagnetic flowmeter to the process pipe. Performing this function under a condition where the process fluid is not at zero flow may cause measurement errors.
Page 85: Setting Of Built-In Counter Reset Value
5-5-3. Setting of built-in counter reset value Set a start value of the built-in counter. The scale of this value is considered as the weight of the pulse. Carry out the built-in counter reset in section 5.4.5 to start totalization from any totalized value.
Page 86 5-5-4. Setting of built-in counter reset value Reset the built-in counter to start totalization from a value set as the built-in counter reset value. If this value is set to 1000, the built-in counter starts totalization from 1000 after the counter is completely reset.
Page 87: Setting Auto Spike Cut
5-5-5. Setting auto spike cut This function eliminates steep noise spikes (spike noise) in the flow rate. Noise generated when foreign matters collide with electrode is an example of the spike noise. When the flow rate changes sharply, this function holds the outputs according to the damping time. Generally the spike noise occurs in a few milliseconds and settles down within the output holding time and the outputs are not affected.
Page 88: Setting Moving Average Processing
5-5-6. Setting moving average processing This function is used to carry out the moving average processing of the measured flow rate values. The model MTG performs the flow rate calculation every 400 ms. For example, if the moving average process time is set to 2 seconds, the moving average processing will be carried out 2 sec.

Page 91 Mechanism of electrode status diagnostic function Detect empty pipe condition or scale on electrode condition by monitoring flow rate signal. Once the flow rate signal fluctuates over a certain threshold, the device judges that the flowtube is empty or scale appears on the electrodes. There are five threshold levels to meet an environment where the device is installed.
Page 92: Setting Parameters
Operation conditions  The grounding work must be securely carried out (grounding resistance 100 Ω or less).  The fluid conductivity must be 30 µS/cm or greater.  The noise level must be higher than or equal to the set threshold value when the pipe is empty.

Page 94 Step Procedure Screen Repeat steps 1 to 5 to set SENSITIVITY MID or SENSITIVITY LOW, SENSITIVITY LL or SENSITIVITY LLL to check if the function also detects the empty or scale on electrode status with the converter's display. Depending on whether the empty status is detected in each setting, the result falls into one of the following.
Page 95 Step Procedure Screen Next, fill fluid into the pipe. If the scale appears on the electrodes, clean the electrodes and fill fluid. Check that the empty or scale on electrode status is not detected in this condition. Since it takes at least 30 seconds to clear the empty or scale on electrode status after fluid is filled in the pipe, perform checking when 30 seconds or more have passed after fluid is filled.
Page 96 Step Procedure Screen (Branch 4) „ When the result is (4) in Step 8 (Continued) Check that the empty or scale on electrode status is not detected when SENSITIVITY MID has been set.
