The RTM3 flowmeter is equipped with pressure compensation and ensures a constant and accurate flow rate. The meter operates at the same pressure as the network pressure and is not sensitive to back pressure. The extended scale of the instrument improves the reading accuracy of lower flow rates in the 5 l/min and 15 l/min versions. A one-piece polyamide scale cover reinforces the structure and improves its impact resistance. The patient cannot touch the scale.

The flowmeter control knob is designed for high reliability and easy cleaning. A polyamide seat ensures the tightness of the knob. The knob is guaranteed leak-proof for five years when closed. A metal strainer in the inlet of the flowmeter protects the device from gas network impurities and thus protects the patient.

The body is made of nickel-plated brass. Each flowmeter unit has a serial number engraved on the body for identification and traceability. The flowmeter is MRI compatible.
