Our client has multiple customers on a DC power supply system and needs to know the watt hours (W.hr) or kilowatt hours (kW.hr) used by each customer. Texmate installed a Tiger 320 Series DI-50E meter to measure the DC volts from the power supply on Channel 1 and the DC amps from a DC shunt on Channel 2. The meter records the result of Channel 1 x Channel 2 as W.hr or kW.hr and continually displays this on the operational display.
Demand and peak demand are important measurements for large consumers of electricity. This is because the price utilities charge for electricity is related to the peak usage of the consumer over the billing period.
The **Electronic Demand Meter** from Texmate is ideal as a submetering system that can measure and track demand and peak demand in different parts of the factory. This information can then be used to manage the overall peak demand strategy of the factory.
If the real-time clock option is installed in the **electronic demand meter**, the meter can log or print the time the peak demand occured.
The 6 setpoints can be used for load switching or alarms.
If an IWO2 watt input module is installed, the amps, volts, frequency kW, and kWh power factor readings can be viewed by using the UP and DOWN buttons.
Our customer requires a quality control test for watt/hour rating of electrical appliances. The test is carried out over 5 minutes. A Texmate DI-50E meter with a watt input module is installed. The meter is programmed to totalize the watt/hours when the start button is pressed. The meter totalizes the watts for 5 minutes and the watt/hour rating is held on the display.
As a programmable meter controller (PMC), the Tiger 320 Series is adaptable to one-off final assembly and quality control test jigs. The modular design of the PMC and the vast choice of input signal conditioning modules, allows production engineers to overcome many quality control challenges.
