Description

Tokyo Ryuki Kogyo EA Series Differential Pressure Flow Meter

For small flow rates of gas and water, instantaneous flow rate indication and integrated flow rate display can be performed. The flow rate is output as a 2-wire DC4 to 20mA signal. The straight pipe part is incorporated and it is stable. The transmitter has a compact body of about 600g, and is compact and lightweight. Easy-to-read LCD display with backlight Tube fitting connection possible AIR flow rate: 1 NL / min to 500 NL / min series.

Core Operating Principle

Capillary Transmission: Pressure taps upstream and downstream divert pressure signals through impulse tubing directly into a magnetic or diaphragm-driven differential pressure element.
Local Mechanical Indication: The sensing diaphragm drives a local mechanical pointer across a calibrated scale, delivering clear flow rate readings directly on site.

Features

Tokyo Ryuki Kogyo EA Series Flow Meter

Power-Free Local Indication: Utilizes a direct mechanical diaphragm dial pointer for local flow rate monitoring without external electrical supply.
Orifice Wafer Assembly: Measures differential pressure ( $Delta p$ ) across an internal primary orifice element to calculate liquid, gas, or steam volumetric flow rates.
High System Compatibility: Mounts between standard ANSI / JIS pipe flanges ( $15text{ mm to }300text{ mm}$ ) across line pressures up to $2.0text{ MPa}$ (2 $20text{ bar}$ ).

Applications

Marine Engine Cooling Lines: Monitoring cooling water and seawater circulation rates in shipboard machinery spaces.
Industrial Utility Lines: Local flow tracking for boiler feed water, steam distribution, and plant compressed air mains.
HVAC Chilled Water Systems: Balancing and monitoring chilled/hot water loop flow rates in large facility management systems.
