Intelligent Water Flow Meter with Totalizer (JH-FM-2610)

                                                                        Intelligent Flow Totalizer

The intelligent flow totalizer is a kind of instrument that deal with the orifice, vortex, turbine etc. flow sensor signal through process signal, operation, display, communication ect. process convert as flow signal. Using high-performance microprocessors, combine the advanced algorithm and reliable hardware circuit of the organic together, thus make the totalizer can work in bad industrial site. The totalizer not only has the evolution, accumulate, alarm and communication functions but also have the special function such as can realize button release alarm, sensor break-line alarm output function. Fully meet the needs of different users in different occasions. Adopts 5 digits highlight LED display instantaneous flow and nine highlight LED display total flow way, solved some problems in some applications that the short of display digits.
 
Application:

-All kinds of liquids, steam, general gas and etc. Have been widely used for flow totalizing, measurement and control in Biology, petroleum, chemical, metallurgy, electric power, medicine, food, energy management, aerospace, machinery manufacture and other industries.

 
Features:

- Modularized structure and hardware compatible with other AI series instruments and modules, which make it easy to maintain and quick delivered.
- Modularized and configurable inputs. The flow input can be 1-5V, 0-5V, 4-20mA or frequency signal, and special user defined input specification is also available. The temperature input can be configured to Pt100 RTD, K, E, J type thermocouple, voltage, or current signal. The pressure input can be various voltage or current signal.
- Abundant functions such as retransmission, high/low alarm of momentary flow, temperature and pressure, abnormal signal detecting, and communication with computer are available.
- Square root/no square root selectable ,8-digits accumulation value and 4-digits momentary process value, small signal cut-out can be set at any range.
- It has perfect temperature and pressure compensation used for general gas, saturated steam, overheat steam and liquid. The compensation calculation with the method of table look-up has a high accuracy in the steam measurement application. Special function can be carried out by enhancing the compensation formula upon customers' demand.
- Advanced computation algorithm assure enough accuracy in the application of flow measurement even if the frequency input signal is very small.
- As used as batch controller, it has 4-bit accumulator for control and 12-bit accumulator for total sum individually.
- With high precision current module installed, the totalizer can provide retransmission with 14 bit output resolution and 0.2%FS output precision.
