Hydraulics & Hydrology – S series, H series
Design and manufacture of equipment for engineering education and research. Constantly evolving for the growing demands of the engineering education sector.
Vernier Hook & Point Gauges
The Armfield H1 Vernier Hook & Point Gauges are ideal for the measurement of steady state water surface position, as is frequently needed during hydraulic investigations.
Series Liquid Manometers
A range of general purpose laboratory manometers using liquid displacement to measure differential pressure.
Computer Compatible Manometer Bank
The Armfield H14/2 is designed to replace banks of manometers when used in conjunction with a number of Armfield products. 16 simultaneous pressure measurements can be displayed on a user-supplied computer, and the information data logged.
Laboratory Flumes and Channels for Hydraulic Teaching and Research Studies
Armfield Ltd has been designing and supplying open channel facilities (flumes) to hydraulic laboratories throughout the world for over 50 years. We have now introduced a new suite of standard research flumes, both tilting and fixed bed, available in several working lengths and a variety of operating modes. Also added to the range are computer control and data logging packages for S6MkII flumes.Hull University Total Environment Simulator
River Flow Simulator
The Armfield S17 simulation tank demonstrates river feature formation, including flow and bed load motion, making an excellent introduction to the study of fluvial geomorphology and can also demonstrate sophisticated and advanced concepts for research purposes.
Glass Sided Tilting Flume
One of the most important tools to the hydraulics engineer, the S6MkII laboratory flume features a wide range of optional instruments and models to offer extensive demonstration capabilities in all aspects of open channel flow.
Advanced Hydrology Study System
The S12 demonstrates significant physical processes found in hydrology and fluvial geomorphology, including rainfall hydrographs for catchment areas of varying permeability, and the formation of river features and the effects of sediment transport.
A range of Pitot tubes for the measurement of water velocity in open channels and closed ducts.
Propeller Velocity Flowmeter
Used to measure and record very low point velocities in water and other conductive fluids, the H33 uses the change in impedance of a rotating multi-bladed impeller to indicate rotational speed caused by the flowing fluid.
Wave Probe System
A simple and robust instrument for the measurement and recording of water waves in hydraulic models and ship tanks, which works on the principle of measuring the electrical conductivity between two parallel wires.
Laser PIV System
The compact, portable H41 Laser PIV System uses particle image velocimetry to measure, non-intrusively, fluid velocities at multiple points in a flow, at rates of up to 16Hz. An ideal, cost effective tool for research and demonstration.
Portable Pressure Meter (0 – 2000mBar)
A versatile, hand held, battery operated portable pressure meter capable of measuring pressures of water or air from 0-2,000 mbar (0-1,500 mmHg).
Portable Pressure Meter (0 – 140mBar)
A versatile, hand held, battery operated portable pressure meter capable of measuring pressures of water or air from 0-140 mBar (0-99.99 mmHg).
Miniature Propeller Probes
Each probe consists of a sensing head that is mounted at the end of a slim stainless steel stem. A co-axial connector at the top of the stem allows the probe to be connected to the H33-10 Digital Indicator.
Digital Hook & Point Gauges
A direct indicating gauge, which eliminates observation errors due to vernier and scale reading. It can be set to zero anywhere in the operating range to permit easy relative level checking.
The Armfield H33-10 Digital Indicator has been developed for use with the miniature propeller probes H33- 1/2/3 where laboratory or field measurement of water velocity is required.
An adjustable mounting tripod constructed from aluminium alloy, supported by three stainless steel rods secured by thumbscrews. For use with Armfield Hook & Point Gauges and Pitot Tubes.
Drainage and Seepage Tank
Practical demonstration and visualisation are essential elements of fluid flow study. The S1 Drainage and Seepage Tank has been designed to allow students to conduct a highly visual experimental study of flow through permeable media.
Mobile Bed and Flow Visualisation Tank
Practical demonstration and visualisation are essential to fluid flow study. The S2 enables students to conduct experimental studies of flow through permeable media, including mobile bed situations and two dimensional flow visualisation.
The S10 demonstrates, on a small scale, the relationship between rainfall and runoff from catchment areas of variable permeability, and the abstraction of ground water by wells, with or without surface recharge from rainfall.
Ground Water Flow Unit
The S11 provides a small-scale demonstration of the hydrological principles of ground water flow, and their relevance to certain engineering constructions. Particularly suitable for the study of sub-surface water flows.
Hydraulic Flow Demonstrator
The S16 operates as an accessory to the F1-10 Hydraulics Bench, offering a highly visual demonstration of flow through both open channels and close conduits. Includes a unique elevating bed section, and models of various hydraulic structures.
Sediment Transport Demonstration Channel
This improved version of the Armfield Sediment Transport Demonstration Channel enables the demonstration of the full range of bedforms that arise in a mobile bed as the flow and/or slope are increased.
