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 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 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.
The fluid flows from bottom to top through the meter tube of the flowmeter. The float is lifted until an annular gap between the measuring cone and the float is produced which corresponds to the flow. The forces acting on the float are in equilibrium. The height of the float resulting from the flow rate is transmitted by the permanent magnet in the float through the magnetic tracking system in a rotation to the pointer axis of the analog indicator unit. The variable-area flowmeter consists of a stainless steel device with an integrated conical stainless steel measuring tube and a vertically movable float. The valve for setting the flow rate is built-in (only KDS-K/C).
The flow meter-monitor PPS is a flow monitor for nominal pipe sizes greater than NW 32. Fluid flow (regardless of direction) deflects the paddle and, via an eccentric, moves a magnet holder fitted to a permanent magnet.
The magnet actuates non-contacting a dry-reed switch embedded in the switching tube. The paddle switch is available with N/O contact or N/C contact. The inlet and outlet pipe section should be approximately three times the nominal size of the piping. The flow monitor can be fitted in a standard T piece or reducing pipe. Ideally the flow monitor should be fitted in horizontal piping.
