What is a stilling well and its purpose?

The purpose of a stilling well is to dampen waves or surges while permitting the water level in the well to rise and fall with the major fluctuations of the main body of water or flow channel. The water level in the well can be measured and used to calculate flow or to control devices such as gates or pumps.

What is a stilling well in tank?

Stilling wells are cylinder-shaped chambers that are connected to, but isolated from, a channel’s main flow of water. Capturing a portion of water inside of a stilling well helps to quiet the interfering turbulence found in the main channel.

What is a stilling box?

: a depression in a channel or reservoir deep enough to reduce the velocity or turbulence of the flow. — called also still box. — compare orifice box.

What is the purpose of the stilling well in hydrometry?

The stilling well protects the float from debris and ice and dampens the effect of wave action.

What is Innage and ullage?

Alternate Ullage Gauge – The ullage obtained by subtracting the measured height of the liquid in the tank from the official reference height of the tank. Innage Gauge (Dip, Sounding) – The height of the liquid surface from the bottom of the tank (or datum plate).

What is radar level transmitter?

Radar Level Transmitters offer reliable non-contact, maintenance free continuous measurement of liquids inside metal tanks or vessels. Perfect for use with corrosive liquids, thick fluids, slurries or other applications where direct contact with the media would not be desired. …

What is the stilling basin and its types?

Stilling Basins: A stilling basin is a basin-like structure in which all or a part of the energy is dissipated. The stilling basins commonly used for spillways are of the hydraulic jump type, in which dissipation of energy is accomplished by a hydraulic jump.

What are the types of stilling basin?

Abstract

• SAF basins;
• USBR basins;
• Bhavani basin, and.
• VNIIG basins.

What is hydrometric data?

What hydrometric data are measured? The two main water quantity variables are water level, and streamflow (also known as discharge). However some stations also collect and publish other environmental parameters such as air and water temperature.

What is discharge hydrograph?

A hydrograph is a graph showing the rate of flow (discharge) versus time past a specific point in a river, channel, or conduit carrying flow. The rate of flow is typically expressed in cubic meters or cubic feet per second (cms or cfs).

What is Innage in ship?

Meaning of “Innage” It is the distance from the top of the cargo to the bottom of the tank. It is the opposite of ullage.

What is Innage in tanker?

Innage Gauge (Dip, Sounding) – The height of the liquid surface from the bottom of the tank (or datum plate). Swing Gauge – See Alternate Innage. Ullage (Outage) Gauge – The distance from the liquid surface to the top of the tank (or reference point).
