GE RHM 04 Manuel utilisateur

RHM 04

The RHM 04 can measure ow rates up to 10 kg/min

(22 lb/min) with extremely fast response times and

excellent repeatability. A very high pressure version

up to 1067 bar is also available, manufactured by

GE’s Rheonik mass owmeter experts.

Applications

• General control • Dosing • Mixing

• Batching • Injections • Filling

Features

• Available as very high pressure version up to 1067

bar

• Response times of 30 ms and better

• Flow uncertainty down to 0.10%

• Repeatability better than 0.05%

• Unique torsion oscillator

• Typical measuring ranges from 0.1 to 10 kg/min

• Minimal ows as low as 50 g/min

• Customization possible

• Extra compact design with minimal space

requirement

• Hazardous Area Approvals (ATEX, CSA, ...)

Versatile Coriolis Mass

Flowmeter with Fast

Response Times for Very

High Pressure Applications

Advantages

• Torsion oscillator design assures most stable and

basically drift free measurement and increased

signal to noise ratio

• Not sensitive to changes in pressure

• Longest life time and increased safety (low stress

in welds and increased wall thickness against

abrasion)

• No moving parts, practically no maintenance

• Removable connection manifold available

Pressure Rating RHM 04

The maximum pressure (pmax) of a sensor is determined by its weakest part. The weakest part can be the measuring

loops (pmax indicated below) or the construction type (pmax indicated in the Basic Order Code section, last page) or the

selected anges / ttings (for pmax please see respective standard).
