High Performance Pressure Sensor – 10m Water Gauge (Flush Diaphragm)
The high performance pressure sensors are ideally suited for measurements in hydraulic models.
This high performance pressure is designed for 10m water gauges. Mounted with a flush diaphragm, this pressure sensor is suitable to measure impact pressures on structures. If you would like to measure water depth and wave pressure under rubble mounds or pressure in pipes and other vessels, high pressure sensors threaded with a protective nose cone are better fit for these purposes.
High pressure sensors with flush diaphragm for 5m and 10m water gauges are also available from this website.
Diaphragm and cables
The all welded diaphragm and body are manufactured from 316 stainless steel.
The sensors are supplied with a 10m length of vented cable, which has an internal vent tube and strainer wire. Alternative cable lengths can be ordered on request.
Digital display unit option
The user can choose to purchase their pressure sensors equipped with a digital display unit, which shows pressure in a range of parameters.

Marine, Naval, Hydrodinamic and OceanographTowing Carriages
HR Wallingford design towing carriages for marine research institutes, universities and educational institutes.
HR Wallingford self-propelled carriages are installed on rails above towing tanks, sea-keeping and manoeuvring basins, ocean basins, flumes or ice tanks. They are used to tow scaled, instrumented models through still water, waves or ice. They supply a wide range of sizes and configurations, from small educational carriages for university laboratories, through to high speed towing carriages for ship design evaluation and research. They also design and supply multi-axis motion carriages for sea-keeping and manoeuvring basins and ocean basins. These have an integrated sub-carriage for forced model manoeuvres using a towing system, as well as the ability to track free-sailing models.
HR Wallingford build carriages for tanks from 1.5 up to 50 metres wide. The carriage speed and rails are tailored to the type of tests, vessels and model scales that the facility is designed for. For example slow, carriages with speed accuracy for ice tests or high speed carriages for naval applications.
Towing carriages for research institutes
These carriages can be either manned or unmanned and are typically more than six metres wide and over 100 metres in length with speeds greater than six metres per second. The self-propelled carriages are used for mounting precise instruments to measure forces and moments.
We know that every project is unique; our expert team will work with you to develop a bespoke towing carriage solution that meets your specific requirements.
Towing carriages for universities and educational institutes
HR Wallingford design and build towing carriages for smaller research facilities based in universities and educational institutes. These carriages are designed for towing tanks from two metres or four metres wide, with a minimum length of 40 metres up to a maximum of around 60 metres. The carriages are typically designed to run at a maximum speed of three metres per second, but can run up to four metres per second if the tank is long enough.
They unmanned carriages are light weight, rigid and robust platforms that can carry a wide variety of equipment.
Instrumentations for use with carriages
HR Wallingford offer a full range of instrumentation for use with both they carriages or existing carriages. These include:
1. Resistance dynamometers
2. Self-propulsion dynamometers
3. Open water propeller dynamometers
4. Surface or underwater model force measuring balances
5. Detachable carriage mounted large amplitude horizontal planar motion mechanisms
6. Vertical planar motion mechanisms for underwater model manoeuvring testing
7. Model clamps and guiding arms(0 reviews) -
Marine, Naval, Hydrodinamic and OceanographARCboat
The ARCboat is a remote controlled boat that is used to collect river and estuarine data including flow, depth and suspended sediment concentrations. It was developed in partnership with end-users and perfected to meet their exact needs. The boat can carry a variety of Acoustic Doppler Current Profilers (ADCP) and other instruments when required.
HR Wallingford provides outstanding customer support throughout the ownership of an ARCboat, from delivery to ongoing training and support.
Key features
- Can carry a variety of ADCPs and other instruments
- High quality data collection with minimal underhull air entrainment
- Robust and reliable design
- Excellent manoeuvrability
- Designed with operator safety in mind
- Lightweight and easy to transport
- Unique detachable bow
- Can also be used to measure environmental conditions in lakes
