Basic Set up of the Schneider Electric / Foxboro LG01 Guided Wave Radar Level Transmitter

Foxboro LG01 Guided Wave Radar Level TransmitterThe Foxboro Model LG01 Radar level measurement transmitter provides very accurate and reliable level measurement for the widest choice of installation and application.

Guided Wave Radar Technology 

Electromagnetic pulses are emitted and guided along a probe. These pulses are reflected back at the product surface. The distance is calculated by measuring this transit time. This device is perfect for high-end applications. It is suitable for applications with foam, dust, vapor, agitated, turbulent or boiling surfaces with rapid level changes.

This video demonstrates the quick set up of the instrument.

What are In-line Drain Separators?

In-line (drain) separators
In-line (drain) separator.
(Armstrong)
Condensate in steam and air piping reduces thermal efficiency, causes water hammer, corrodes equipment such as valves and pipes, and causes other problems.

In-line (drain) separators separate condensate efficiently by using the centrifugal force of steam or air created by introducing it into a specifically shaped path. Because of the simple structure of the drain separators, pressure loss is minimized, enabling clean, dry steam or air to be fed to equipment.

When steam or air flow enters the drain separator, centrifugal force is generated in the fluid because of the device’s internal structural design. The fluid drains along the wall because of the difference in specific gravity with steam or air, eventually striking the baffle. The baffle guides the fluid to the drain outlet and to the trap, which drains it. As a result, small dirt particles and condensate are separated and removed from the system through the bottom drain.

Features:
  • Cyclone structure maximizes liquid separation efficiency
  • Pressure loss is extremely low
  • No moving parts means no breakdowns

Ashcroft Materials Compatibility and Corrosion Guide

Below is a very good materials compatibility and corrosion guide courtesy of Ashcroft.

The reference is intended to serve solely as a general guide in the recommendation of materials for corrosive services and must be regarded as indicative only and not as any guarantee for a specific service.  There are many conditions which cannot be covered by a simple tabulation such as this, which is based on uncontaminated chemicals, not mixtures.

Many of the chemicals listed are dangerous or toxic.  No material recommendation should be made when there is insufficient information, a high degree of risk, or an extremely dangerous chemical.  The end user is responsible for testing materials in his own application, or for securing the services of a qualified engineer to recommend materials.

The end user is responsible for the choice of product(s) in his own application, based upon his own determination of the materials, chemical, and corrosion factors involved. THIS GUIDE AND ITS CONTENT ARE PROVIDED ON AN “AS IS" BASIS WITHOUT WARRANTY OF ANY KIND.
