2. USING
Oval gear flow meter is a pointer count accumulated round devices and light devices to zero volume flow meter is widely used in various industrial areas of the liquid flow control, applicable to all types of liquid measurements, such as crude oil, diesel , petrol and so on, with great range and high precision, convenient use and maintenance of the characteristics of different materials selected to meet the petroleum, chemical, pharmaceutical, food, metallurgy, electricity, transportation and other fields of liquid flow measurement.
3. THE WORKING PRINCIPLE AND STRUCTURE
Flow meter is installed in the metering tank and the measurement of a pair of oval box gear, with the upper and lower cover an early Lunar sealed cavity (due to rotation of the gear, so sealing is not an absolute) as a unit of emissions. When measured by the pipe into the liquid flow meter, due to pressure generated by the Impor t and Expor t Depar tment to promote a pair of differential gears for rotation, the constant measurement by cavity after the beginning of the
Lunar liquid delivery to the exit, elliptical gear with each revolution time displacement is the product of four times the measured volume of liquid flow (the principle of Figure 1).

Operation manual
9.4.5 4-20mA Zero set and full set
Wiring according to wiring diagram, connect with ampere meter, and get through external switching power supply.(12V or 24V)
(1) Zero setting: Entering to page P07 from parameters setting, press s , moving to parameters value, and then press + or . When parameter's value changes, ampere meter's changes accordingly. The smaller the P07 value is, the smaller the current is. When ampere meter value is 4mA, press s , move to P07, flashing, and then press + , showing P08 parameters, zero setting end, and enter to full setting.
(2) Full setting: parameters adjust to P08, steps as zero setting. By adjusting parameters, make ampere meter value to 20mA. When setting end, save as step 7.4.4 and then exit.
9.4.6 The method of flow segmented
Flow ratio defers from different flow meters. Especially when min flow rate gap is big, the measuring range will be influenced. But digital counter could overcome it by flow segmentation comparison. Instruction is as follows:
(1) When instantaneous flow adopt the unit of m
3
/h (P09=0), and actual instantaneous flow ≤P11, use P00 for pulse equivalent.
When P11<actual instantaneous flow≤P12, use P01 for pulse equivalent.
When P12<actual instantaneous flow≤P13, use P02 for pulse equivalent.
When P13<actual instantaneous flow≤P14, use P03 for pulse equivalent.
When actual instantaneous flow>P14, use P04 for pulse equivalent.
(2) When instantaneous flow adopt the unit of L/M(P09=1), and actual instantaneous flow ≤P15, use P00 for pulse equivalent; when actual flow ≥P18, use P04 for pulse equivalent.
(3) If without adopting flow segmentation, using one pulse equivalent, then just need to set P22 to. In this situation, P00 is pule equivalent for any flow rate.
7.4.7 Instrument adjusting method
(1) When adjusting instrument, set P22 to 0 firstly (no flow segmentation)
(2) Flow meter works at the middle flow, adjusting P00 pulse equivalent, making flow meter showing data equal to filling data.
(3) Choosing instantaneous flow unit, namely P09 is 1 or 0.
(4) Set P10 to be 1.
(5) Set P06 to be about 1/3 of the min flow. When instantaneous flow<P06,instantaneous flow shows 0.
(6) If without flow segmentation compensation, instrument adjusting ends; if with flow segmentation compensation, then follow step (7).
(7) According to the instantaneous flow of instrument, adjusting flow rate to min flow, calculate the equivalent by measuring tank and write it down. Adjust the flow to different flow ranges, and respectively calculate the corresponding equivalent.

10. CAUTION
1.
No water flow meter test.
2. To start or stop when the gate valve should be slow to prevent a sudden shock, and should prevent back flow.
3. Flow meter repair, there shall be no demolition of the rear cover so as to avoid re-generated when the impact of changes to the precision accuracy.
10.1 Calculation and adjustment of deviation
(A) the basic error of flow meter, flow test points by the time measured were determined using the following equation: (volume method)
E=Vm- V/V×100%
E-meter error (generally refers to the cumulative error) the two digits.
Vm meter measured value (that is, that value)V, as amended, the flow meter measured the value of the standard device (that is, the actual value) from the basic formula for calculating the error, when Vm> V, the basic error of flow meter "+" value, said flow meter go faster.
Vm <V, the basic error of flow meter "" values that take the slow flow meter.
In order to make the basic error in the flow meter error limit is often the need for error. That is installed in the counter through the replacement of a pair of adjustment gears (adjusted teeth) to change the mechanical transmission ratio, so that the flow meter to adjust the show deserves.
Error can not change the flow meter to adjust the flow characteristics, so that it curves in artificially in the new coordinate system.
In general, the provisions of (or actual use of) the flow range of the maximum and minimum flow test point margin of error of not more than the basic provisions of the basic error of precision limit can be adjusted through the error so that the basic error of flow meter qualified .
Flow meter has been used, the general regulation of first gear with the original error test group, and then the error in accordance with the specific error to adjust the situation further.
