The Hydrological Services Absolute Shaft Encoder model AD375MA & AD375MAL is low power, microprocessor controlled shaft encoder designed for field operation to enable measurement of water level in well and dams. The internal CMOS circuitry enables the encoder to output measured levels in absolute format.
The GCO1-P Gas Chamber Orifice permits the use of extremely low bubble rates with increased accuracy and near total reduction of lag between actual level rise and orifice pressure.
The Ground Feeler Device is a mechanical spring loaded attachment that is used in conjunction with any gauging winches fitted with Amegraph cable and connected to Columbus pattern gauging weight.
The Hornet Sediment Sampler has been developed to perform river and stream sediment sampling from fixed cableways using conventional suspended sediment samplers such as D49. The Hornet Sediment Sampler is an ideal solution for retro fitting to an existing manned cableway system, thus minimising the personal injury risk associated with this type of sampling.
The Advanced Bubbler System Model HS-40 has been designed to replace conventional nitrogen gas bottle supply to bubble units/gas purge systems for measuring water level in dams, rivers, canals and tanks with up to 30 mH2O (100 ft).
