CURRENT AND FLOW METERS
Current Meters and Open Channel Meters have been a speciality of Valeport's since the company was first formed in 1969. From traditional impeller mechanism to high-accuracy electromagnetic type, Valeport has a solution to meet your requirements. Configurations suitable for a variety of applications are available, from hand held measurements in the smallest streams to self-contained instruments in the deep ocean.
Modern day signal conditioning electronics and filtering techniques allow highly accurate measurements to be made, and there is a choice of sensor shapes and sizes to suit the application. The solid state sensors and standard titanium / polyurethane construction provide excellent corrosion resistance, and depth ratings up to 5000m. Contact us to discuss your requirements and decide on the right instrument for the job.
VRS-20 Radar Level Sensor
The VRS-20 is a pulsed k-band radar level sensor developed by Valeport to work seamlessly with the TideMaster tide logger, operate standalone with optional integrated GPRS telemetry or interface to a third party data logger. Versatile and simple to install, the VRS-20 addresses a number of the issues traditionally associated with water level measurement. Non-contact technology removes the installation, corrosion & fouling issues of submerged sensors, while simplifying datum control. Accuracy and performance are unaffected by changes in water density and atmospheric conditions.
Tidemaster Portable Tide Gauge
The TideMaster is a small, cost effective Water Level Recorder, specifically designed for applications where the user requires an accurate record of water height, but with the added option of meteorological data via a ultrasonic wind speed and direction sensor. Suitable for use in fresh or salt water, the TideMaster can be deployed for up to 1 year, dependant on the sampling rate, with instrument set up and data retrieval via an optional display panel or using the PC software supplied. Alternatively, the system can be supplied with radio modules for real time data transmission.
MIDAS WLR Water Level Recorder
The MIDAS WLR replaces the popular Model 730T as Valeport's Water Level Recorder / Seabed Tide Gauge. Designed for long or short term deployments in offshore environments, or locations where a traditional shore based tide gauge is impractical, the MIDAS WLR may be moored in line or to the seabed. The standard instrument is fitted with a 0.01% accuracy pressure sensor and acetal housing for up to 500m depth rating, with a deep water titanium housed option also available.
miniTIDE Self Recording Tide Gauge
The miniTIDE is a small Tide Recorder, designed for short term underwater deployments. Fitted with a 0.01% temperature compensated piezo-resistive cell, the miniTIDE will record high accuracy pressure data for a period of 1 month at a 10 minute sampling interval, using a single alkaline C cell. This makes it ideal for use in short term projects or for academic studies. Available with a choice of pressure ranges, and with either 500m acetal or 6000m titanuim housings.
