The Hydrologic Instrumentation Facility (HIF) has four sections within its organizational structure; [34] the Field Services Section which includes the warehouse, repair shop, and Engineering Unit; the Testing Section which includes the Hydraulic Laboratory, testing chambers, and Water Quality Laboratory; the Information Technology Section ...
This modification - supplied by the USGS Hydrologic Instrumentation Facility - is available in two sizes: the original 3" and the recently added 6". [28] Kilpatrick notes that the discharge for this modification of the Parshall flume is slightly greater than for a standard Parshall flume of the same size. [29]
The first version of SDI-12 was released in 1988. It was designed by a coalition which included the U.S. Geological Survey's Hydrologic Instrumentation Facility (HIF) and a group of private companies. [2] The SDI-12 Specification is maintained by a non-profit corporation called the SDI-12 Support Group.
The first routine measurements of river flow in England began on the Thames and Lea in the 1880s, [2] and in Scotland on the River Garry in 1913. [3] The national gauging station network was established in its current form by the early 1970s and consists of approximately 1500 flow measurement stations supplemented by a variable number of temporary monitoring sites.

Some varieties of flumes are used in measuring water flow of a larger channel. When used to measure the flow of water in open channels, a flume is defined as a specially shaped, fixed hydraulic structure that under free-flow conditions forces flow to accelerate in such a manner that the flow rate through the flume can be characterized by a level-to-flow relationship as applied to a single head ...
The Building 440 is an insulated, refrigerated hangar. There is an office and instrumentation building, a cold-weather engine test cell, the refrigeration system, mechanical-draft cooling towers, and a steam-heating plant. [4] The main chamber is 252 feet (77 m) wide, 201 feet (61 m) deep, and 70 feet (21 m) tall at the center of the hangar.
The Westbay MP system is a modular instrumentation system for multilevel groundwater monitoring acquired by Nova Metrix in 2015, the MP system consists of two parts: (1) the casing system and (2) portable probes and tools that provide a compatible data acquisition system. The Westbay casing system is designed to allow the monitoring of multiple ...
A water tunnel is an experimental facility used for testing the hydrodynamic behavior of submerged bodies in flowing water. It functions similar to a recirculating wind tunnel , but uses water as the working fluid, and related phenomena are investigated, such as measuring the forces on scale models of submarines or lift and drag on hydrofoils .
