- Mechanisms using hydraulic cylinders are used in various applications such as vehicles and production equipment.
High-precision display and data output of stroke volume is required for automation, labor saving, visualization, improvement of work accuracy, time saving, and other purposes.
- High-resolution flow sensor converts into a pulse signal that is resistant to long-distance transmission noise, even over long distances to the control panel.
Voltage output is possible in a control panel with low noise, enabling high-precision measurement.
- If you purchase a flow sensor and counter as a set, COCORESEARCH will prepare a setting value table, change the setting values to match the usage conditions, and ship the product from the factory.

Counter Setting Example
1）
In case of piston diameter A=100mm and rod diameter B=40mm
The pressure receiving area (shaded area) C = 502 x π - 202 x π = 6597.3 mm2
2）
When the piston moves 1mm, the amount of oil returned from the cylinder D = Cx1= 6597.3x1 = 6597.3mm3.
3）
Since flow rate E = 245mm3/Pulse per tooth (pulse) of flow sensor VC0.2
D / E = 6597.3 / 245 = 26.928 Pulse when the piston moves 1mm.
4）
The piston travel per pulse is E/C = 245/6597.3 = 0.0371364 mm.
5）
Enter and set the value of item 4) to the above counter with item 1 (mantissa part): 371364 and item 2 (exponent part): 7.

What we can do with measurement
- High-resolution flow sensors and our unique Periomatic™ calculation method allow detailed monitoring of cylinder behavior from very low flow rates.
- High-precision measurement even when the measurement target and control panel are far apart, thanks to noise-resistant pulse signals that can be transmitted over long distances.
- Analog and digital outputs with fast update times display and measure cylinder movement.
- CAN communication automatically outputs measurement data at each update time, reducing program development costs (depending on model).
Measurement data other than CAN communication is acquired by command response method
