The plastic level switch NKP is designed for economical control of liquids in vessels. Many industrial applications can be realized with two different plastic versions each with three different mountings. The switch is remarkable for its maintenance-free design, small dimensions and reed contacts with high switch capacity.
The switch is mounted on the side of the vessel. A hinged plastic float with a magnet floats up and down through the liquid level. The encapsulated reed contact is operated by the magnet. The switching function (N/O contact / N/C contact) is determined by the installation position. The switching function is reversed by simply rotating the switch through 180°.

OverviewApplicationsMore information The operation of the model KAL-... electronic flow monitor is based on the calorimetric principle. The end face of the sensor is heated to a few degrees above the temperature of the flow medium. When the medium flows, the heat generated in the sensoris transferred to the medium, ie, the sensor is cooled. The cooling procedure is an accurate measure of the flow velocity. The sensor signal is compared with the reference data stored in microcontroller. An alarm signal and/or an analogue signal (4-20mA) that is proportional to the flow velocity is output if the actual flow velocity deviates from the desired flow velocity. The microcontroller allows the flow indicator to be easily claibrated and the temperature to be compeansted.
Function of the unit The electronic flow monitor model KAL-D...continuosly monitors flowing media. It finds service in all applications where flow currents with minimum pressure loss are to be accurately monitored. the one-part design of measuring probe considerably reduces dirt sensitivity Operating principle The electronic flow monitor model KAL-D....works according to the calorimetric principle. The sensor tip is heated to a few degrees above the temperature of the flowing medium. When the medium flows, heat generated in the probe is dissipated by the medium. In other words, the probe is cooled down. This coding sequence is a precise measure of the flow velocity. The sensor signal is compared with reference data stored in a microcontroller. An alarm signal is generated when the desired flow velocity is reached. Simple calibration and optimal temperature compensaiotion is achieved with a micro-controller. Temperature compensation Temperature compensation in the KOBOLD flow monitor is achieved by a microcontroller. All information necessary for temperature compensation is programmed at the factory. The devices can easily be adjusted by the customer to the process conditions. Due to the adaptation of the sensors to the operating data the sensors switch absolutley consistently even with large temperature gradient.

KOBOLD NBK bypass level indicators are used for continuous measurement, display and monitoring of liquid levels. The bypass tube is attached onto the side wall of the vessel.
NGM uses TDR (Time Domain Reflectometry) technology, which is also known as Guide Microwave or Guided Wave Radar. This means that low-energy and high-frequency electromagnetic impulses, generated by the sensor’s circuitry, are propagated along the probe which is immersed in the liquid or solid to be measured. When these impulses hit the surface of the media, part of the impulse energy is reflected back up the probe to the circuitry which then calculates the level from the time difference between the impulses sent and the impulses reflected. The sensor can output the analysed level as 4 ... 20 mA analogue output, or it can convert the values into freely programmable switching output signal.

The KOBOLD Gear Wheel Flowmeter series DZR have been designed for a flow measurement for viscous liquids. The measuring unit consists of a pair of gear wheels which is moved by the flow according to the principle of gear wheel motor. The bearings are – according to the material combination – either ball bearings or gliding bearings. The movement of the gears is sampled without contact by means of two sensors located in the cover. Between sensor compartment and measuring chamber is located a pressure-resistant, non-magnetic separator plate. The different versions vary through housing materials, bearing assembly, through the medium being used and the accuracy. The mounting position and flow direction is arbitrary.
The Kobold gear wheel flow meter model KZA for viscous liquids is a low-cost flow meter. The movement system consists of a gear set propelled by the flow. The instrument movement bearing is designed for the types KZA-1810 and KZA-1865 as radial and axial gliding bearings. The type KZA-1816 has a ball bearing.
The pick-up is separated from the measuring chamber and registrates the gear resolution contactlessly through the housing wall.
Easy maintenance, slight pressure loss, small weight and low noise level are the outstanding features of this flow meter.
Applications
The flowmeter of the series KMT, based on the measurement principle of thermal mass flow, is ideally suited for the measurement of flow of compressed air and gases in pipes with sizes from DN 15 ... DN 700. Measurement of for instance the usage of compressed air, nitrogen, CO2, O2 or other non-corrosive, non-flammable gases. The KMT is setting new standards in terms of measurement accuracy and reproducibility thanks to its application specific adjustment during production. This flowmeter is adjusted under a pressure of 7 bar (abs) (DN 15 ... DN 50) or 9 bar (abs) (DN 65 ... DN 700). Adjusting the device specifically for its application has the advantage of keeping the actual flow speed in the pipeline low even with very large flow quantities. Thanks to the more stable flow profile, this low flow speed facilitates a much better degree of reproducibility and accuracy than if the device were adjusted conventionally under normal pressure, as flow speeds up to 200 Nm/s can often no longer be controlled under conventional adjustment pressures. The core design of the flowmeter is based on the hot film sensor element, which is produced using the most modern thin film technology and has already proven itself time and time again in the automotive industry. This flow sensor features excellent long-term stability, a fast response time and an extremely high degree of reliability. Two outputs are available, for further processing of the measurement data. Depending on the application, these outputs can be configured as analogue (current or voltage), switch output or as pulse output for the measurement of the consumption. The KMT has an integrated counter for consumption. The consumed amount is shown on the display and the saved value is not lost even after power outage. The availability of the consumption amount as a free configurable pulse output is another helpful feature.
The fluid flows from bottom to top through the meter tube of the flow meter. The float is lifted until an annular gap between the meter ring and the cone-shaped float is produced which corresponds to the flow. The forces acting on the float are in equilibrium.
The new model DMW-... direct mass flow meter has been specially designed for use in gas measuring technology. An inexpensive analogue output is fitted. The model DMW is available in three versions: with or without integrated 3 ½-digit LCD display or with a 8-digit counter. The direct stream procedure is ideally suited for measurements from 0,5 Nl/min (max.) up to 6000 Nl/min air (model: DMW-B*786). In case of small flow rates the measurements are taken with a bypass-system (DMW-A/C). In contrast with most volumetric flow meters the mass flow meter DMW-... has no moving parts, and no temperature or pressure correction is required. The meter may be installed in any position and the pressure loss is negligible. The simple mechanical construction ensures the highest degree of reliability when used with aggressive gases, and under tough industrial service conditions.
The Bolod vortex flow meter DVH utilises three primary sensing elements: a vortex-shedding velocity sensor, an RTD temperature sensor and a solid-state pressure transducer to measure the mas flow rate of gasses, liquids and steam.
Systems that use external process measurements may not provide adequate compensation for the fact that process conditions can change radically between the point of velocity measurement and the point where upstream or downstream pressure and temperature measurements are being made. Because the DVH multivariable flow meter measures all of these parameters in a single location, it delivers a more accurate process measurement.
Integrating multivariable output capability with a single line penetration also simplifies system complexity and helps reduce initial equipment cost, installation cost and maintenance costs.
