The Kobold Differential Pressure Transmitter model PAD is a micro processor-based high performance transmitter, which has flexible pressure calibration and output, automatic compensation of ambient temperature and process variable, configuration of various parameters, communication with HART ® protocol. The application is very various, as measuring pressure, flow and level by application method. All data of sensor is to be input, modified and stored in EEPROM. As an option the Kobold Pressure Transmitter is also available as a flow meter. This flowmeter model PAD-F has added the totalizing function in the PAD transmitter. So it is available to check the flow rate and totalizing flow. It measures the flow rate by using differential pressure without compensation of temperature and static pressure. The shape of the PAD-F is the same as the standard device and it is only the terminal block which is different since there are two more terminals for the read-out of the pulse output.

The new KOBOLD type DUK flow meters are used for the measurement, monitoring, metering and dosing of low viscosity fluids. The devices work on the principle of the difference in running times. This is based on the fact that ultrasonic waves in a medium are influenced by the speed of flow. Two sensors mounted opposite one another in the pipeline function simultaneously as transmitter and receiver of ultrasound signals. If there is no flow, then the running times of both signals are identical. If the medium is flowing, then the running time of the signal against the flow is longer than that with the flow. The running time difference, which is determined by a microprocessor, is proportional to the speed of flow. The devices can be equipped with a switching output, a frequency output or an analogue output. In addition, a compact circuit can be selected that features a digital display, a switching output and an analogue output. The device series is rounded off by an optionally available dosing and meter circuit. The meter circuit indicates the momentary flow rate in the first line of the display and the partial or total quantity in the second line. A dosing circuit controls simple filling tasks and similarly measures flow rates, total amounts and filling amounts. The analogue output and two relay outputs can be used for further processing of the signals
Compact wire-actuated encoder with a max. measurement length of 2000 mm and an analog output.
The NGR is a level sensor that uses TDR technology (time domain reflectometry) and thus can be used in oil- and waterbased liquids without calibration. The NGR’s guided radar uses time-offlight technology to measure electromagnetic pulses. The time difference between the sent pulse and the reflected pulse is used to calculate the level, both as a continuous value (analogue output) and a freely positionable switching point (switching output). Due to its flexible probe that can be changed or cut, it is possible to integrate the sensor quickly into any application. The NGR can work in deposit-forming and foaming liquids. The sensor’s intuitive setup uses four buttons and a display to ensure quick and easy adaptation to the application.
