Rotamass LR compact Coriolis flowmeter

Thursday, 30 August, 2012 | Supplied by: Yokogawa Australia Pty Ltd


Yokogawa Electric Corporation has released the Rotamass LR Coriolis mass flowmeter.

Designed to measure both liquids and gases, the effective turndown of the flowmeter is no less than 2000:1 for liquids and 5000:1 for gases and the mass flow measurement range spans from 1.5 g/h to 40 kg/h, achieving a measurement accuracy of ±0.15% for liquids and ±0.5% for gases.

The flowmeter’s dual bent tube optimally decouples the core measuring element from process vibration that can cause fluctuating zero stability and decrease measurement accuracy. When fluid density changes, a single-tube Coriolis flowmeter can become unbalanced and start to behave like an emitter. The Rotamass LR remains balanced due to the equal mass change in both tubes and the absence of interference from the process piping.

By design, it is insensitive to fluctuations in the ambient temperature and achieves good zero stability under changing process conditions. The two tubes are made from C-22 alloy, which is less susceptible to thermal expansion than conventional stainless steel.

Normally it is more difficult to measure temperature with Coriolis flowmeters that have tubes with a smaller surface area. The Rotamass LR uses an inline temperature sensor, ensuring precise and fast measurements in process temperatures ranging from -50 to +150°C.

The flowmeter has a gas-tight, all-stainless-steel secondary containment that can handle pressures up to 65 bar. It can be used in high-pressure applications up to 400 bar. The flowmeter does not use gaskets, minimising the risk of leaks.

Insulation and a heat jacket are available as options.
