 MEASURING NOT SPECIALLY ADAPTED FOR A SPECIFIC VARIABLE; ARRANGEMENTS FOR MEASURING TWO OR MORE VARIABLES NOT COVERED BY A SINGLE OTHER SUBCLASS; TARIFF METERING APPARATUS; MEASURING OR TESTING NOT OTHERWISE PROVIDED FOR (means structurally associated with lightning or other overvoltage discharging apparatus for recording the operation thereof G 01 R; displaying information in general G 09 F; recording in a way which requires playback through a transducer G 11 B)
 

Notes

(1)

 This subclass covers:
 

-

 devices for indicating or recording the results of measurements, not peculiar to variables covered by a single other subclass;
 

-

 analogous arrangements but in which the input is not a variable to be measured, e.g. a hand operation;
 

-

 details of measuring instruments, which are of general interest;
 

-

 measurement transducers not adapted solely for the measurement of a single specified variable and not provided for elsewhere, i.e. means for converting the output of a sensing member to another variable where the form or nature of the sensing member does not constrain the means for converting;
 

-

 measuring or testing not otherwise provided for.

 Attention is drawn to the Notes following the title of class G 01.

 

 

 
 

 1
/ 00 Measuring arrangements giving results other than momentary value of variable, of general application (G 01 D 3/00 takes precedence; in tariff metering apparatus G 01 D 4/00; transducers not specially adapted for a specific variable G 01 D 5/00; computing G 06)

1
/ 02 • giving mean values, e.g. root mean square values (measuring root mean square values of currents or voltages G 01 R 19/02)  

1
/ 04 • giving integrated values (giving mean values G 01 D 1/02)  

1
/ 06 • • by intermittent summation  

1
/ 08 • • • over fixed periods of time  

1
/ 10 • giving differentiated values  

1
/ 12 • giving a maximum or minimum of a value  

1
/ 14 • giving a distribution function of a value, i.e. number of times the value comes within specified ranges of amplitude  

1
/ 16 • giving a value which is a function of two or more values, e.g. product, ratio  

1
/ 18 • with arrangements for signalling that a predetermined value of an unspecified parameter has been exceeded (G 01 D 1/14 takes precedence; for a specified parameter, see the subclass relevant to this parameter, e.g. level of a liquid exceeded G 01 F, temperature exceeded G 01 K) [3]  
 

 3
/ 00 Measuring arrangements with provision for the special purposes referred to in the subgroups of this group

3
/ 02 • with provision for altering or correcting the transfer function  

3
/ 024 • • for range change; Arrangements for substituting one sensing member by another [6]  

3
/ 028 • mitigating undesired influences, e.g. temperature, pressure [6]  

3
/ 032 • • affecting incoming signal, e.g. by averaging; gating undesired signals [6]  

3
/ 036 • • on measuring arrangements themselves [6]  

3
/ 04 (transferred to G 01 D 3/028)

3
/ 06 • with provision for operation by a null method  

3
/ 08 • with provision for safeguarding the apparatus, e.g. against abnormal operation, against breakdown  

3
/ 10 • with provision for switching-in of additional or auxiliary indicators or recorders  
 

 4
/ 00 Tariff metering apparatus (tariff meters for measuring the time integral of electric power or current G 01 R 11/56 ; in taximeters G 07 B 13/00; coin-freed mechanisms therefor G 07 F)

4
/ 02 • Details  

4
/ 04 • • Resetting-mechanisms, e.g. for indicating members (for mechanical counters G 06 M 1/28)  

4
/ 06 • • Arrangement of clutches between driving and indicating member, e.g. of hysteresis clutch (G 01 D 4/04 takes precedence)  

4
/ 08 • • Transfer of indication from a counter into a summing counter (mechanical counters G 06 M)  

4
/ 10 • Maximum indicating or recording apparatus, i.e. where the tariff for a period is based on a maximum demand within that period  

4
/ 12 • • Apparatus for indicating or recording progressive maximum  

4
/ 14 • • Fixed-demand indicating or recording apparatus, i.e. where indication is made when a predetermined quantity has been consumed during a time interval greater or less than a predetermined time interval  

4
/ 16 • Apparatus for indicating or recording maximum or minimum load hours  

4
/ 18 • Apparatus for indicating or recording overconsumption with opposing torque which comes into effect when a predetermined level is exceeded, e.g. subtraction meters
