2. GENERAL
Combined with a flowmeter and a shutoff valve, the batch counter passes a predetermined amount of the
process fluid in batching operations. Built around a single chip microprocessor, this versatile, compact, and
lightweight counter is designed for ease of operation.
It saves time and effort in many processes, such as blending materials, dosing with additives, transferring
materials from one tank to another, or shipping from an outlet, at chemical, food, paint plants or elsewhere where
streamlined production lines are desired.
2.1 Features and Functions
(1) Easy operation.
a. As setting, start, stop, and reset of batch quantity are carried out with touch panel in front of measuring
instrument and push button switches, assured operation is possible.
b.
The display part is equipped with color LCD module with 3.5-inch touch panel. Although it is small, it is easily viewable.
c.
Start and stop, and reset are operated with push button switches and setting of batch quantity is operated
with touch panel to prevent wrong operation.
(2) Wrong setting can be prevented.
As the operation of touch panel can read out nine types of batch quantities that have been registered, wrong
setting can be prevented.
(3) Correct quantitative control is possible.
a.
As an operation signal that opens or closes the valve at 2 stages, correct quantitative measurement is possible.
b.
As the overshoot quantity due to response delay of valve can be corrected by setting the forecasted overshoot
quantity, correct quantitative operation is possible.
(4) A system can be configured easily.
As start stop, and reset operations are enabled by external signal and the batch completion output can be
obtained, the interlocking with other control system is enabled easily.
(5) The safety of process can be ensured.
a.
The valve is operated by 2-stage open and 2-stage close. The generation of static electricity in piping or tank when the
operation is started is prevented and piping shock due to water hammering when the valve is closed is prevented.
b.
If a defect is generated in the process and the pulse is not input or fluid leaks exceeding the setting batch quantity, an
alarm signal will be output.
(6) This device is of high reliability and the maintenance can be implemented easily.
a. As the internal configuration is unitized, this device is of high reliability and the maintenance can be
implemented easily.
b. All I/O systems are isolated by photocoupler / relay etc.
c. When the power supply is turned OFF, total flow value and each setting value will be held in FeRAM.
