Tokyo Ryuki Kogyo RM-1000 Mass Flow Meter

Description

The basic configuration of the mass flow meter consists of a thermal mass flow sensor, a bypass laminar flow element, and a bridge circuit. An electric current is passed through the resistor wound around the sensor to generate heat. When a part of the gas that enters from the inlet flows into the sensor, the temperature distribution of the sensor changes, which is captured by the bridge circuit and taken out as a flow rate output signal.

Equipped with a digital display for visualization of the flow rate, Instantly grasp the flow rate with a digital display, Easy wiring with a display , Output is 1 to 5V or 4 to 20mA , Equipped with a jog switch for easy range switching, Compact cylindrical design makes installation easy (any mounting location), Originally developed flow sensor with less error, Controller can be retrofitted.
