Industrial Toxic and Combustible Gas Detection Technologies: A Recorded Webinar


Industrial gas detectors are used in a wide variety of chemical plants, refineries, water treatment plants, and other manufacturing facilities to continuously monitor and detect toxic or combustible gases and vapors. They are equipped with audible and visual alarms to alert personnel to the existence of these conditions.  The major components for industrial gas detectors are the sensor, the detector, the transmitter, and the annunciator.  Gas detection systems are available as single point sensing or multiple point sensing capabilities, and in fixed position or portable configurations.

This recorded webinar, presented by MSA, provides an excellent overview of the history of gas detection and the technologies used today. MSA is the world's leading manufacturer of safety products designed to protect people throughout the world.

Celebrating Those Who Serve Our Country and Protect Our Freedom

Veterans Day

Veterans Day is not just another holiday. It honors those Americans who fought for our freedom. By celebrating our Veterans, we continue to tell the story of how this country became the most powerful on Earth - through bravery, honor, truth, and determination.

Our Veterans are our neighbors, friends, family, and co-workers. They took an oath to defend the United States and our Constitution, from all enemies, foreign and domestic. We must never forget their bravery, service, and sacrifice.

Instrument Specialties thanks our Veterans, past and present, for serving our country and protecting our freedom.

Remote Actuator Controls Provide Safer, More Efficient Wastewater Treatment Application

Above ground wastewater valve controls
Above ground wastewater actuator controls.
A wastewater treatment plant installed six new AUMA SAR electric actuators for modulating duty to control the dosing of chemical additives. These actuators are used for modulating duty to handle the high-precision dosing of short-chain fatty acids, used to support the growth of microorganisms and help to remove phosphorus from the wastewater. 

The actuators are situated below ground, with their AC actuator control systems mounted above the ground. This is done for both for both safety and convenience. This arrangement is made easy thanks to the modular design of AUMA actuators. AUMA actuator controls can be mounted up to 325 feet from the actual actuator (motor and gearbox).

When workers have to access equipment underground, it requires special safety needs and procedures. These include the use of qualified personnel and gas detection tests to ensure sufficient oxygen as well as to rule out flammable of explosive potentials. Locating the actuator controls above ground level, in combination with non-intrusive actuator versions, reduces underground work to a minimum, thus helping to save time and cost.

Below ground wastewater valve controls
Below ground motors and gearboxes.
The split-level installation also provides diagnostic and local control from a more comfortable position. The graphical interface and all operational, data logging and diagnostic features provided by the intelligent AC actuator controls are easily accessible. These actuators also use Profibus DP-V1 to communicate with the plant’s main distributed control system. Local AUMA Service took care of installation and commissioning on site.

Seametrics iMAG Series Electromagnetic Flowmeter

The Seametrics iMAG-Series is the most economical flanged electromagnetic flowmeter on the market. With electrodes designed to discourage fouling, it is available in 3” to 12” pipe in municipal or industrial water, waste and reclaimed water, pump stations, and packaged plant applications. Minimal straight pipe requirements allow iMAG-Series meters to be used in piping configurations where there is little space between the meter and an elbow.

iMAG-Series meters are CE certified, certified to NSF/ANSI standard 61 and are rated IP68 for applications where the meter may be operated under water to a depth of at least 10 feet (3 meters) continuously.

The display can be meter mounted or remote, and both rate and total indication are standard. Rate and total units and pulse scaling can be set via the front panel touch key pad by the user.

Bidirectional flow reading is standard with totals available in forward, reverse, net flow, batch forward flow, and batch reverse flow. Batch totals can be reset.

A power/output cable allows outputs for use with a variety of Seametrics and other displays and controls for remote reading and telemetry applications. Pulse output is standard on all models and 4-20mA passive current loop is standard on the iMAG 4700p. In addition, 4-20mA loop, HART protocol, high speed digital, and Modbus® protocol outputs are optional on the externally powered units, depending on model.

The SOR 815 LT Submersible Level Transmitter


The SOR 815LT transmitter is a rugged, compact, loop-powered instrument that accurately and reliably measure levels for many types of liquids. The SOR 815LT indicates level by continuously monitoring the static pressures of the liquids, using high-performance pressure sensors. The 815LT has a corrosion-resistant 316 stainless steel, seal welded housing, and a high-density Polyethylene (HDPE) cable jacket for compatibility with most liquids. A PVC self-flushing nose cone can also be provided to prevent clogging, or standard configuration offers dual 1/4” NPT female / 1/2” NPT male connections for rigid mounting. The transmitters are vented at the surface through a tube in the cable to reference atmospheric pressure.
