Flow Measurement in Subsurface Pipes



Ultrasonic flow measurement, properly configured, can be the preferred solution for flow measurement in water and wastewater pipes, especially those in subsurface locations. Demands for increased monitoring of system flow at numerous points throughout a network or system create a need to install flow measurement instrumentation on existing pipes that are unlikely to have built-in accommodations for the needed sensors.

Ultrasonic flow measurement transducers are mounted on the exterior of existing piping and require no pipe cutting or service interuption to install. The rugged transducers are suitable for subsurface installation and provide long term uninterupted operation. Ultrasonic flow measurement functions over a wide range of flow, providing accurate data during normal, peak, and off-peak hours. The data derived from the measurements can also be used for leak detection. Data output from the instrument can be used locally or transferred by a number of methods to remote monitoring stations for system wide analysis.

The video provides some additional application advantages of ultrasonic flow measurement for subsurface pipe applications. Share your flow measurement challenges of all types with process measurement specialists. Leverage your own knowledge and experience with their product application expertise to develop effective solutions.

Keeping up to date on the latest product information....

Fox Thermal Instruments, an acknowledged innovator in thermal mass flow technology and instruments, has released a flow meter targeted for gas flow measurement in the oil and gas industry. The FT4X delivers a long list of advanced and useful features for flare and waste gas monitoring, gas studies, royalty and allocation, and general gas flow research.

The instrument utilizes a constant temperature differential technology to measure gas or air mass flow, employing two precision RTD sensors. One temperature sensor follows the media temperature, while the other is heated by the instrument electronics to maintain a constant temperature differential between the two sensors. The amount of applied heat to maintain the differential is proportional to the mass flow rate. A linearized 4-20mA output signal is the final output of the transmitter.

The flow meter is available for inline or insertion installation, along with another variant that features retraction of the instrument from the line without flow interruption. Various probe lengths accommodate line sizes to 70 inches. Flow bodies, flow conditioners, and other accessories are available to customize the instrument assembly to fit each application.

There is a wealth of additional information provided in the brochure included below. Share your flow measurement challenges and requirements for process measurement specialists. Leverage your own knowledge and experience with their product application expertise to develop effective solutions.

Asset Condition Monitoring for Major Equipment

turbine blades
Asset and equipment monitoring promotes the maximizing
of productivity by reducing downtime.
Minimizing machine or system downtime, for whatever cause, is a common productivity and financial goal of industrial processing of all types. Lost production time can never be recouped, and unplanned equipment outages can cost millions. There is real benefit to be had from monitoring operational aspects of machinery and systems in real time.

Asset condition monitoring, as the name implies, is the process of continually monitoring a machine or piece of equipment with the intent to alert operators to anomalies in machine function. Data gathered can also be used to define a normal operating envelope and show trends that may indicate a need for service. The goal, ultimately, is to repair, adjust or maintain prior to and avoiding outright failure. Key indicators of failing equipment can be changing values in vibration, noise or temperature measurements. Monitoring these and other variables, some derived at very localized and specific points, provides key indicators of the condition of the machine. By evaluating trends in the data, intelligent systems can provide health information about the equipment and assist in the early detection of possible faults or failures.

Implementation of asset condition monitoring is benefiting manufacturing plants and process industries such as chemical, petrochemical, pulp and paper, power generation, wind turbine, and oil and gas. Not only can it save money from protecting against unplanned outages, but condition monitoring also improves productivity, quality and profitability.

GE's Bently Nevada 3500 Monitoring System provides continuous, online monitoring suitable for machinery protection and asset condition monitoring applications. It is the company's most capable and flexible system, with a traditional rack-based design. The useful features of the system are numerous, and it delivers advantages not provided in other systems. Share your major asset monitoring challenges and plans with a systems specialist, and leverage your own knowledge and experience with their product application expertise to implement an effective solution.
