Webinar - The Latest on Teledyne LaserFlow, Extreme Applications - July 25

Water and Wastewater Webinar: The Latest on LaserFlow, Extreme Applications Wednesday, July 25, 2018 10:00 AM CST Speaker: Rick Dey, Key Accounts Manager - Flow Meter Products This webinar will discuss how the LaserFlow is being used where other technologies have failed. Low velocity, high velocity, deep or shallow water; situations like these are no problem for the LaserFlow. The LaserFlow™ velocity sensor remotely measures flow in open channels with non-contact Laser Doppler Velocity technology and non-contact Ultrasonic Level technology. The sensor uses advanced technology to measure velocity with a laser beam at single or multiple points below the surface of the wastewater stream. The sensor uses an ultrasonic level sensor to measure the level and determines a sub-surface point to measure velocity. The sensor then focuses its laser beam at this point and measures the frequency shift of the returned light. An industry first, a touch-button interface for an intuitive user experience and tool-free operation. The LaserFlow is ideal for a broad range of wastewater monitoring applications. SafeSwap enables safe and quick replacement of gas sensors without turning off the instrument. During submerged conditions, flow measurement continues without interruption with optional continuous wave Doppler Ultrasonic Area Velocity technology. With its specially designed mounting bracket in place, the LaserFlow can be deployed and removed from street level. This avoids the risk and expense of confined space entry. A variety of communication options enable programming and data retrieval from a remote location. Information about data quality can be recorded and transmitted with the flow data. Additionally, built-in diagnostic tools simplify installation, maintenance, and advanced communication options reduce site visits. Register for Webinar Here!

Happy Fourth of July from Instrument Specialties!

Mining Operations Optimize Dewatering Processes

Effective water management is critical to both open-pit and sub-surface mining operations. Mine dewatering is an essential part of resource extraction, as it lowers the water table around the mine or quarry. Effectively managed dewatering processes typically employ continuous water level monitoring. Mine dewatering is usually undertaken for several reasons:

• To ensure stability of mine walls during and after excavation—In open-pit mines, a water table that is too high can destabilize mine walls, haulage roads, and slopes. Water pressure reduces the stability of mine walls and can lead to sliding and collapse of materials in the slope. In underground mines, the inflow of water must be controlled to prevent flooding; however, a balance must be maintained so that groundwater levels are not needlessly depleted.
• To optimize mine production and reduce operational costs—Effective dewatering operations create dry conditions so that low strength aquifer sequence materials (sands, gravel, and clays) can be safely excavated, reducing drilling and blasting costs. Additionally, wear and corrosion on equipment is minimized, and the possibility of pump burn out is reduced by accurately monitoring drawdown. Haulage costs for unsaturated excavated material is significantly less than for saturated materials, further reducing operational cost.

Active Stormwater Runoff Monitoring

Stormwater runoff is a major contributor to surface water pollution, perpetuating ever-increasing state and federal demands for stormwater runoff control and reporting. A wide range of flexible instrumentation enables Teledyne Isco to meet non-point source discharge monitoring requirements.

Regulating Stormwater Discharge

The National Pollutant Discharge Elimination System (NPDES) Stormwater Program regulates stormwater discharges from potential sources that include both point and non-point sources. Operators and managers of storm sewer systems, construction sites, croplands, industrial sectors, and urban areas may be required to obtain authorization to discharge stormwater, in accordance with both federal law, and often more stringent state and local regulations.

To meet these requirements, businesses, municipalities, and other organizations must develop comprehensive stormwater monitoring programs. These programs typically consist of several parts, including the collection and storage of storm event data on rainfall, flow, and measured pollutant levels, as well as taking water samples during the storm event for laboratory analysis. Representative sample collection is dependent upon crucial factors such as timing, flow volume, and water quality.

Rapidly changing storm conditions can present several challenges to accurate sample collection, monitoring of system status, program adjustment needs, and data retrieval. With instrumentation from Teledyne Isco, a site-specific system can provide precise automatic sampling with real-time data collection and flexible programming. All of this and more can be achieved from remote locations.

Remote Monitoring + Sampler Commands

The 2105C (CDMA) and 2105G (GSM) Cellular Interface Modules allow the user to remotely enable an Isco Model 6712 portable or Avalanche portable refrigerated wastewater sampler while simultaneously monitoring current site conditions, with flow and water quality data logged and transferred to a secure server database. Immediate access to data and the ability to send commands to a sampler from off-site can reduce labor and fuel costs. Additionally, the user can wait until a storm has passed to retrieve the samples, meaning safer working conditions.

Basic Operation

The primary functions of the system are:

• Log real-time water quality and flow data
• Automatic sampler enabling by predetermined conditions
• Push data to secure server 
• Remotely enable/pace sampler
• Retrieve sampling reports

What is Inferential Measurement? An Understanding Through Differential Pressure Level Control

Level control using delta-P transmitter.*

Differential pressure transmitters are utilized in the process control industry to represent the difference between two pressure measurements. One of the ways in which differential pressure (DP) transmitters accomplish this goal of evaluating and communicating differential pressure is by a process called inferential measurement. Inferential measurement calculates the value of a particular process variable through measurement of other variables which may be easier to evaluate. Pressure itself is technically measured inferentially. Thanks to the fact numerous variables are relatable to pressure measurements, there are multiple ways for DP transmitters to be useful in processes not solely related to pressure and vacuum.

An example of inferential measurement via DP transmitter is the way in which the height of a vertical liquid column will be proportional to the pressure generated by gravitational force on the vertical column. The differential pressure transmitter measures the pressure exerted by the contained liquid. That pressure is related to the height of the liquid in the vessel and can be used to calculate the liquid depth, mass, and volume. The gravitational constant allows the pressure transmitter to serve as a liquid level sensor for liquids with a known density. A true differential pressure transmitter also enables liquid level calculations in vessels that may be pressurized.

Gas and liquid flow are two common elements maintained and measured in process control. Fluid flow rate through a pipe can be measured with a differential pressure transmitter and the inclusion of a restricting device that creates a change in fluid static pressure. In this case, the pressure in the pipe is directly related to the flow rate when fluid density is constant. A carefully machined metal plate called an orifice plate serves as the restricting device in the pipe. The fluid in the pipe flows through the opening in the orifice plate and experiences an increase in velocity and decrease in pressure. The two input ports of the DP transmitter measure static pressure upstream and downstream of the orifice plate. The change in pressure across the orifice plate, combined with other fluid characteristics, can be used to calculate the flow rate.

Process environments use pressure measurement to inferentially determine level, volume, mass, and flow rate. Using one measurable element as a surrogate for another is a useful application, so long as the relationship between the measured property (differential pressure) and the inferred measurement (flow rate, liquid level) is not disrupted by changes in process conditions or by unmeasured disturbances. Industries with suitably stable processes - food and beverage, chemical, water treatment - are able to apply inferential measurement related to pressure and a variable such as flow rate with no detectable impact on the ability to measure important process variables.
