Introducing the next generation Hydra-Pulse 235 - a continuous non-contact water level measurement sensor that is versatile, easy to use and program. Installation is simple and since the sensor measurement is non-contact (installed above the water) accurate water level measurements can be taken even in flood conditions without possibility of damage to the sensor. The new Hydra-Pulse 235 has a proven mean time between failure (MTBF) of more than 50 years, and is the most accurate in the industry with a measure- ment accuracy of 2mm up to 115 ft (35 m). HYDRA-PULSE 235 SDI -12 Non-Contact Radar Level Sensor • Industry best +/-2mm accuracy to a measuring distance of 115 ft (35 m)* • Accuracy unaffected by rain, humidity, dust, temperature or vibration • 4-20mA & HART • Optional dual SDI-12 outputs (with HartBeat & HartBeat Plus) • Remote sensor configuration (with HartBeat Plus) • Completely waterproof and dustproof • 50+ years Mean Time Between Failure (MTBF) • Corrosion resistant powder coated aluminum construction • Optional stainless steel for highly corrosive environments • Completely maintenance free • Easy installation * Hydra-Pulse 275 available with 2mm accuracy up to a measuring distance of 246 ft (75 meters) OVERVIEW FEATURES

OVERVIEW
FEATURES
The Hydrological Services HART to SDI-12 / Modbus Interface allows any 4-20mA HART device to be connected to an SDI-12 Data Logger and/or an RS485 Modbus RTU providing the best accuracy available from the HART protocol.
HartBeat
All the features of the HartBeat with additional high quality LCD display. The Hydrological Services HART to SDI-12 Interface allows any 4-20mA HART device to be connected to an SDI-12 Data Logger and/or an Analog RTU providing the best accuracy available from the HART protocol.
HartBeat PlusHydra-Pulse 275
Hydra-Pulse 275 with a measuring distance of up to 246 ft (75 m) and industry best 2mm accuracy.
Radar Configuration with the HartBeat Interface
Radar Configuration with the HartBeat Plus Interface
In continuous non-contact level measurement with radar, the sensor sends microwave signals towards the water from above. The surface of the water reflects the signals back in the direction of the sensor. Using the received microwave signals, the sensor determines the distance to the product surface and calculates the level from it.
The adjustment of the Hydra-Pulse is carried out via the display module or via a PC with the adjustment software PACTware and corresponding DTM. Further adjustment options are possible via a HART Communicator such as the HartBeat and HartBeat Plus
