About PARSHALL FLUME
Specification:
PARSHALL FLUME
The Parshall Flume is an economicaland accurate way of measuring water flow in open channels and non-full pipes.
Originally the flume was developed tomeasure surface waters, water rights apportionment, and irrigation flows.
However, its use has expanded toinclude measuring sewage flow (both in pipe and treatment plants), industrialdischarges, dam seepage, and other applications.
High Precision Flow MeasurementPARSHALL FLUMES are widely recognized for their exceptional accuracy in quantifying open channel flows. Their standardized design ensures consistent performance across various applications, from municipal and irrigation needs to industrial effluent tracking. With a measuring range adaptable to different requirements and a resolution as fine as 0.01 LPS, precise readings are assured under ideal installation conditions.
Durable & Versatile ConstructionConstructed from FRP, Stainless Steel, or Mild Steel, PARSHALL FLUMES offer excellent corrosion resistance and structural integrity. Customizable throat widths, finish options, and mountings allow seamless integration into new or existing channels. Their robust build accommodates demanding environments, both outdoors and indoors, withstanding humidity ranges up to 95% and temperatures from -10C to 60C.
Simplified Installation & MaintenanceDesigned for easy installation, these flumes can be surface-mounted or embedded as required. End connections are available in bolted, flanged, or plain designs to suit varying installation scenarios. Thanks to high durability and smooth inner surfaces, maintenance is minimaltypically involving periodic cleaning to prevent debris accumulation and ensure sustained accuracy.
FAQs of PARSHALL FLUME:
Q: How do you install a PARSHALL FLUME in an open channel?
A: Installation can be done either by surface mounting or embedding the flume in a concrete or metal channel. Proper alignment and levelling are crucial. The inlet and outlet section lengths are standardized based on the chosen model, and compatible end connections (bolted, flanged, plain) ensure a secure fit.
Q: What are the typical applications for PARSHALL FLUMES?
A: PARSHALL FLUMES are extensively used for measuring flow in irrigation systems, municipal water supply networks, industrial effluent channels, and other open flow scenarios. Their versatility makes them suitable for both permanent installations and temporary engineering testing setups.
Q: When should periodic maintenance be conducted on a PARSHALL FLUME?
A: Maintenance intervals depend on the channel and environmental conditions. Typically, low maintenance is required, with periodic cleaning recommended to remove debris and sediment buildup, which helps maintain measurement accuracy over time.
Q: Where can customized sizes of PARSHALL FLUMES be sourced?
A: Manufacturers and suppliers offer both standard and custom sizes. Throat widths range from 3 to 36 as standard, but customized dimensions are available to meet specific site requirements. Equipment can be exported, supplied, or manufactured within India.
Q: What is the process of flow measurement using a PARSHALL FLUME?
A: Water flows through the flumes standardized throat, where depth measurements are taken either manually (scale reading) or via optional sensor output (analog/digital). The calibrated dimensions and design permit calculation of flow rates within the specified accuracy range.
Q: How does using a PARSHALL FLUME benefit an engineering project?
A: PARSHALL FLUMES provide high accuracy (2% of reading), quick response times, and robust performance in diverse operating environments. Their corrosion resistance and adaptability to various end connections and mounting types streamline installation and long-term operation, ensuring reliable flow measurement.
