ZHK 2503N Gas Flowmeter

The ZHK2503N  gas flowmeter consists of a flowmeter module with an orifice, a soap film flowmeter module, a mass flowmeter module, a microcontroller, a display screen, and other components.

Main Features
● Multi-use: The main unit can be used with five different ranges of soap film flowmeters, seven different ranges of orifice flowmeters, and three different ranges of mass flowmeters.
● Touchscreen Color Display: User-friendly interface and simple operation.
● Automatic Display of Conditions: Can automati-cally display volumetric flow rates under four conditions: current conditions, standard condi-tions (273.15K, 101.325kPa), standard condi-tions (293.15K, 101.325kPa), and standard conditions (298.15K, 101.325kPa).
● Digital Calibration Capability: Capable of digital calibration for flow, pressure, environmental temperature, time values, and battery level.
● Data Storage Function: Can store 80 data points per range.
● USB Interface: Option to add a USB drive for data export.
● Bluetooth Printer Option: Supports wireless communication between the printer and the main unit.
● Manual Input Capability: Allows manual input of standard atmospheric pressure and environmental temperature values to minimize measurement errors caused by automatic sensor measurement.
● Built-in Lithium Battery: Battery life exceeds 8 hours.
● Battery Level Display and Over-discharge Protection.Soap Film Section:
● The soap film flow detector utilizes an infrared sensing device combined with microcomputer data processing technology, ensuring high measurement accuracy and effectively reducing human errors.
● The soap film tube has good light shielding proper-ties, preventing sunlight interference and ensuring high reliability.
● Capable of automated calibration of soap film volume values.
● Can automatically record and display the flow values for N measurements (unlimited times), and automati-cally calculate the average flow of the N measure-ments.
● Orifice Section:
Utilizes a high-precision differential pressure sensor for real-time measurement and display of gas flow.
● Mass Flowmeter Section:
Utilizes a high-precision mass flow sensor for real-time measurement and display of gas flow.
