Small Water Flow Meter
The water flow sensor is mainly composed of a plastic valve body, a water flow rotor assembly and a Hall sensor, which is installed in the water inlet end of the water heater for detecting the water flow, when the …
Split Core Current Sensor with 5VDC output
These split core current sensors are cost-effective tools for monitoring single phase AC loads such as fans, pumps, and compressors. The split core design and the self powered electronics make for very simple installation. They are suitable for general monitoring and alarming of HVAC systems for conditions such as a slipped belt or an impending bearing failure.
Three Phase Multi-function Smart Meter
The ME337 Three-phase power meter with Rogowski coils makes for easy retrofit installation on both three and four wire systems. Supports Modbus RTU protocol over RS485 for integeration into building management systems.
Three Phase power meter with 333mV CT
ME237 three-phase multi-functional panel meter supports external 333mV CTs (ME237V),supports 3PH3W and 3PH4W system.
Single Phase Power Meter with CT
The Single Phase Power Meter with internal CT are solid state transducers for measuring the current and voltage of fans, pumps, and other HVAC equipment.The current sensors are available in two types for either AC @ 200A or DC @ 100A applications.The connections are by Modbus.
Split Core Current Transformer, 330mV output
The 330mv AC series of split core current sensors are ideal for installation on existing electrical wiring by snapping around the conductor without requiring and rewiring or interruption of the existing power cabling. UL listed product.The current flowing through the core of this CT produces an output signal from 0 to 330mv ac, proportional to the current. The signal is a low voltage mv ac signal which needs signal conditioning before going into the typical controller.The 330mvac signal is compatible with our T3-6CT and the Wattnode power meter on this site.
Split core Current Transformer, 5A output
The split core current transformer are used for monitoring power of large electrical loads and electrical services. Current flowing in the primary conductor creates a proportional current in the secondary output coil with a range of 0 to 5 amps. This is typically used to drive current indicators on large electrical panels. It is also compatible with commonly used power meters in the industry such as our Three Phase Power Meter.
are ideal where space is limited, such as when metering multiple loads within a panel board. Use for current measurement, energy metering, load surveys, demand metering, energy research, and submetering applications.
