An electrical meter that measures and registers the amount or the integral, with respect to time, of the current that passes through it and is consumed in the circuit. From: Modern Dictionary of Electronics (Seventh Edition), 1999 About this pageSet alert ...
If we extrapolate kh to process conditions in a feed water circuit, i.e. at Re=22×106, the change from the measured kh at Re=4.5×106 is less than 0.1%. An extrapolation in the Reynolds range is therefore feasible if the flow profile is undisturbed. It is intended to validate this ...
It employs a patent balanced lower voltage multi-pulse igniting circuit which increases the anti-interference ability magnificently so that the flow meter will work properly even in demanding industrial environments such as those with power frequency transverter working nearby. Features: * Large...
The STEAM mobile hydraulic system currently being developed in Aachen, Germany uses a number of new features to improve total machine efficiency [4]. Among others is the use of a new independent metering circuit called single edge meter-out control. Unlike other IM configurations, only one ...
The MAXQ3180 supports phase-angle compensation in three load ranges: high, mid, and low. In most designs the sense circuit does not change its phase dependency with respect to loading levels, in which case a single-range calibration is sufficient. However, some low-cost current transformers do...
DDS-1Y Static Single-Phase Electric Energy Meter uses advanced special recording integrated circuit with high precision elements. Mainly used in AC single-phase watt-hour with its recording frequency of 50Hz, it is highly accurate, reliable, durable, low power consumptive, without reversion, creep...
Q: Are thermal flow meters gas specific? A: A thermal mass flow meter is built for a user’s specific operating conditions. Teledyne Hastings' thermal flow meters are thermal based, so measurements are gas specific. For example, there would be a difference in heat conductivity between natural...
between the transducers, whereinfor each transducer with a separate signal generator is provided, and the switching means between the respective signal generator and the associated transducer is disposed,characterized in thatthe transducers (6, 7) directly to the evaluation circuit (26) are connected....
