4. Measuring principle

Vortex flowmeter measures the flow by sensing the vortices in the flow according to “Karman Vortex Street”. When put an shedder in the path of flow, vortices are alternately shed on each side (see picture 4.1)

Picture 4.1: Von Karman Vortex

The frequency of vortices (f) is in direct ratio with velocity of flow (v) and in inverse ratio with width of obstacle (d).

f=St*v/d (formula 1)

v=fd/St (formula 2)

St is Strouhal Number, is a dimensionless constant related to shape of the shedder, which can be get by testing. St is Strouhal Number, is a dimensionless constant related to shape of the shedder, which can be get by test.

Because d and St is constant, flow velocity (v) and average velocity (v0) also have certain relationship ( v0=v/(1-1.25d/D) ), so, you could get v0 by having the frequency of vortices shedding (f) , and then get the mass flow. The ration between quantity of vortex in a certain period of time and the volume of the flow pass by is called coefficient of the instrument (K)

K=N/V (formula 3)

VFM60 series digital vortex flowmeter is designed to provide most reliable performance. This series of vortex flowmeter is designed on Comate Intelligent Sensor PA60 platform .Every parts utilized is universal for all VFM60 series products. The circuit boards use signal isolation and self-diagnose technology.

9.4 The float date format of the instrument

The storage sequence of 4 bits float format is as below:

Address	0	1	2	3
Content	MMMMMMMM	MMMMMMMM	EMMMMMMM	SEEEEEEEE

Use IEEE standard method, do not store 1 on top digit, if top digit is 1, means negative; if top digit is 0, means positive. So the 23 mantissas and a 1 on top digit, which is concealed, constitute a 24 bits fixed point true form decimal, which is a decimal have mantissas less than 1 and more than or equal to 0.5. The lowest 8 bits are exponent-marker using shift code method. The exponent marker equals to the actual value minus 127. For example: 7=86H-7FH, -10=75H-7FH

e.g.:   100=0x00,0x00,0x42,0xc8

-100=0x00,0x00, 0xc2,0xc8

0=0x00.0x00.0x00.0x00 (exponent-marker is 0, the number is 0)

9.5 The sequence of the float date bytes of instrument

Code setting C38 is used for setting the sequence of the float date bytes of instrument. Float date will occupy 4 bytes (2 registers). To set the bytes order of float date, please modify register :

1: LL_LH_HL_HH the lower 16 bytes registers come first, the lower 8 bytes within the 16 bytes registers come first.

eg:  100=0x00,0x00, 0xc8, 0x42

       -100=0x00,0x00,0xc8,0xc2
2: HH_HL_LH_LL the higher 16 bytes registers come first, the higher 8 bytes within the 16 bytes registers come first.
eg:  100=0x42,0xc8,0x00,0x00
       -100=0xc2,0xc8 ,0x00,0x00
3: LH_LL_HH_HL the lower 16 bytes registers come first, the higher 8 bytes within the 16 bytes registers come first.
eg:  100=0x00,0x00,0x42,0xc8
      -100=0x00,0x00,0xc2,0xc8
4: HL_HH_LL_LH the higher 16 bytes registers come first, the lower 8 bytes within the 16 bytes registers come first.
eg:  100=0xc8,0x42,0x00,0x00
      -100=0xc8,0xc2,0x00,0x00

9.6 Modbus error response

When the host sends a command and asks for a correct response, one of below three is going to happen:

1) If the command from the host is correct and processable, the flow meter will give a correct response.

2) If the flowmeter received a command, but detected parity, the error of LRC and CRC will cause no response. The host will process a overtime commend.

3) If the flowmeter received a correct command, but can not process it (read or write a none-existing register etc.), the flowmeter will send a error response

A error response has two byte sections to show its difference from a correct response.

Function code section: In a correct response, the flowmeter will copy the origin function code sent from the host, and the highest bytes of them are all 0(all function codes are smaller than 0x80). In a error response, the flowmeter will set the highest bytes to 1. The host can detect the error code and know the content of the error when it detect that the highest bytes of function codes are 1.

Value section: In a error response, the flowmeter will reply a byte as the error code to definite the content of the error. Please reference to the chart below for the error codes and its definition: 

Code	Name	Meaning
01	Illegal   function code	Flowmeter can not process the function code in a command.   Maybe this function code can only be used on a new device, or it can also indicate that the flowmeter is under error statues.
02	Illegal address	The flowmeter can not process with the address in the command. The initiate  address  plus  address  diversion  are  higher  than  the  highest address.
03	Illegal   contents of value	The content of the value in the command is not acceptable for the flowmeter.
04	Flow         meter function failed	An unrecoverable failure happened when the flowmeter is trying to response.
05	Response	The flow meter will take a long while to process the command. So response this error code to prevent the host from   processing a overtime command.
06	Flowmeter      is busy	To advise the host that the flowmeter is processing a command which will takes a long time. So the host should resend the command when the flowmeter is free.

9.7 Examples of communication
