3 INSTALLATION ALTOSONIC V12 However for storage and/or transportation additional protective measures are recommended. Depending on how long the protection should last one of several methods can be considered: 1. For a storage period of less than one year, the inner pipewall should be protected by a corrosion inhibitor such as Shell Ensys. Do not apply the corrosion inhibitor on the acoustic transducers. 2. For a period of a year or longer, the pipewall should be protected by Tectyl or a similar product.
INSTALLATION 3 ALTOSONIC V12 3.4 Pre-installation requirements INFORMATION! The equipment is designed for safe operation under conditions according to the following classifications: • Pollution degree 2: this means that normally only nonconductive (dry) pollution will occur. Temporary conductivity caused by condensation can occur. • Protection class I: this means the equipment must be earthed. • Humidity: <95% RH • Ambient temperature: -40...+65°C / -40...+149°F • Suitable for indoor and outdoor use.
3 INSTALLATION ALTOSONIC V12 In order to install the gas flowmeter, the pipeline must have a slot of such length that the meter including the gaskets fits nicely in the slot. It should not be necessary to use excessive force to tighten the bolts in order to close the gaps on either side of the meter. Nor should the slot be too small, implying the slot has to be widened by applying brute force to fit the meter and gaskets in the slot.

The meter factor is determined during the calibration and is programmed before the ultrasonic flowmeter is sealed.
SERVICE 8 ALTOSONIC V12 8.1 Periodic maintenance The ultrasonic gas flowmeter does not contain any moving parts. During operation no maintenance will be required such as lubrication or replacing parts that wear out. Therefore during normal operation there will be no need to disassemble the meter in order to gain access to the inner parts of the meter. It is however good practice to make a log file on regular basis, refer to Logging data from a flowmeter on page 66.
8 SERVICE ALTOSONIC V12 8.3 Exchange of transducers Transducers are not likely to break down. In the unlikely situation that a transducer fails, the transducer has to be replaced. Although not strictly required, it is common practice to replace the other transducer on the same acoustic path at the same time. If possible, depressurise the flowmeter. If this is not possible, use the extraction tool to remove the transducer under pressure (maximum 150 bar(g)).

9 TECHNICAL DATA ALTOSONIC V12 9.1 Measuring principle The ultrasonic gas flowmeter operates according to the principle of measuring the transit time of an ultrasonic sound wave. A gas velocity is derived from the difference in transit time of a sound wave travelling in a direction with the flow direction and the sound wave travelling in the opposite direction. The trajectory of the sound wave is called the acoustic path. A chord is the direct path crossing the pipe from one side to the opposite side.
TECHNICAL DATA 9 ALTOSONIC V12 The velocity of the gas is derived from formula (1) and (2) as: An important feature of this method is that the calculated gas velocity does not depend on the speed of sound in the gas or gas properties in general. The gas velocity as calculated is only a function of the measured transit times tAB and tBA; the length of the chord and the angle of intersection of the measuring chord are supposed to be known from the design of the flowmeter.
9 TECHNICAL DATA ALTOSONIC V12 Figure 9-3: Swirl pattern after a single bend Swirl can disturb the gas velocity measurement as the tangential velocity component adds up with the gas velocity measured along one chord. However chords can be arranged in a way to compensate for swirl effects. Two chords arranged in the same plane intersect the flow at opposite angles (cross configuration). These chords respond to the tangential velocity component with the same magnitude but with the opposite sign.

ALTOSONIC V12 MODBUS PROTOCOL DESCRIPTION AND SET-UP 10 10.1 Introduction Modbus communication is based on the master-slave principle. Only the master can initiate transactions (requests), and only the addressed device (slave) responds. The master can also send a broadcast message (“message to all”); none of the slaves will respond to such a message. The flowmeter always acts as a Modbus compatible slave when communicating with host systems. Slaves are identified by means of a “device address”.
10 MODBUS PROTOCOL DESCRIPTION AND SET-UP ALTOSONIC V12 Multiple flowmeters may be connected to the same RS 485 line. In this case only the terminating resistor in the flowmeter at the end of the line should be connected. The terminating resistors in the other flowmeters on the line should be disconnected by means of the switch on the RS 485 driver printed circuit board. Default this switch is set to connect the line terminating resistor.
ALTOSONIC V12 MODBUS PROTOCOL DESCRIPTION AND SET-UP 10 10.3.2 RTU mode Each byte of data is represented in the message by an equivalent number of bits (8). The number of bits transmitted in the process of communicating one byte of information is sometimes also referred to as a “character”. Note that this is not the same as an ASCII character. Standard serial communication parameters Start bits 1 Data bits 8 Parity even Stop bits 1 Error check field Cyclic Redundancy Check (CRC) 10.
10 MODBUS PROTOCOL DESCRIPTION AND SET-UP ALTOSONIC V12 10.4.1 Address Field (Device Address) The address field of a message frame contains: ASCII mode 2 characters RTU mode 8 bits Valid slave addresses are 1...247. Address 0 is used for a broadcast to address all slaves. 10.4.2 Function Field The function field of a message frame contains: ASCII mode 2 characters RTU mode 8 bits Valid function codes are 1...127. The function code tells the slave which kind of action to perform.
ALTOSONIC V12 MODBUS PROTOCOL DESCRIPTION AND SET-UP 10 The contents of the error checking field for the entire message depend on the transmission mode. Error check in ASCII mode transmission For detecting errors in the entire message the error-checking field contains two ASCII characters. The error check characters are the result of a Longitudinal Redundancy Check (LRC) calculation.
