About Dwyer

Dwyer Instruments manufactures and distributes industrial measurement and control equipment, with product lines spanning differential pressure gauges, flow meters, pressure transmitters, and environmental monitoring devices. The brand serves plant engineers and maintenance teams across HVAC systems, compressed-air networks, process automation, and general industrial applications. Dwyer's product portfolio emphasizes analog and digital instrumentation rated for standard industrial environments, with operating ranges and connection standards suited to OEM integration and field retrofit applications.

3G Electric stocks over 389 Dwyer products, including the Magnehelic series of differential pressure gauges (available in ranges from 500 PA to 10 kPa and above), Minihelic II manometers for low-pressure measurement, ultrasonic flow meters (UFM2 series, rated for pipe diameters 0.8" to 6.5"), and current transmitters (CCT series, compatible with 12–24 VDC and 24 VAC supply). Connection options include 1/8" NPT process taps, with dial faces typically 101.6 mm (4 inch) diameter. Temperature operating limits generally span −6.67 to 60 °C for most gauge models. Transmitter units consume minimal power (typically 7 W or 7 VA) and feature isolated analog output for PLC and controller integration.

Dwyer instruments are commonly specified in HVAC commissioning, pneumatic system diagnostics, and industrial airflow verification. 3G Electric supplies these instruments as catalog stock items, enabling same-day fulfillment for Singapore-based customers and expedited shipping to regional and international sites. Technical specifications, connection diagrams, and calibration ranges are available for each SKU to support procurement workflows and system design.

Frequently asked questions

Common questions about Dwyer from 3G Electric.

What pressure ranges do Dwyer Magnehelic differential gauges cover, and which is suitable for HVAC ductwork?

Dwyer's Magnehelic series spans 500 PA, 1 kPa, 10 kPa, and 20 kPa full-scale ranges. For HVAC ductwork and filter monitoring, the 500 PA and 1 kPa models (SKU DWY01216, DWY01110) are standard; the 10 kPa variant (SKU DWY01414) suits higher-pressure applications such as compressed-air line monitoring. All feature 1/8" NPT connections and 101.6 mm dials.

Can Dwyer UFM2 ultrasonic flow meters be used on plastic pipe, and what is the minimum pipe size?

Yes. The Dwyer UFM2-14 (SKU DWY18102) operates on steel, stainless steel, copper, and plastic pipe. Minimum internal diameter is 0.8" (20 mm); maximum is 6.5" (165 mm). Power supply is 12–24 VDC or 24 VAC, with 7 W or 7 VA minimum consumption. Output is isolated analog, suitable for data logging and PLC integration.

What is the temperature operating window for Dwyer Magnehelic gauges, and are high-accuracy options available?

Standard Dwyer Magnehelic gauges operate from −6.67 to 60 °C (−20 to 140 °F). High-accuracy variants are available for critical applications requiring tighter tolerance. Consult the specific model's datasheet (e.g., SKU DWY01414) to confirm accuracy grade and calibration certificate availability.

How do Dwyer CCT current transmitters differ, and what is the input range specification?

Dwyer CCT series includes the CCT 40-102 (SKU DWY60506) and CCT 60-200 (SKU DWY60602). The model designation reflects the current-measurement range; exact input and output specifications vary by type. Both support standard 4–20 mA loop output for SCADA and controller integration. Consult technical data for isolation voltage and response time.

Are Dwyer Minihelic II manometers sealed or vented, and what maintenance do they require?

Dwyer Minihelic II units (SKU DWY01106, DWY01110) are sealed manometers with a liquid-filled diaphragm design, requiring no periodic maintenance or recalibration under normal service. They tolerate vibration and shock better than open-tube designs. Storage in a temperature-controlled environment (−20 to 50 °C) preserves long-term accuracy.

What is the process connection standard for all Dwyer Magnehelic models supplied by 3G Electric?

All Magnehelic models in stock feature 1/8" female NPT process connections (duplicate high and low pressure taps on differential models). This standard allows direct integration into pneumatic, HVAC, and industrial measurement manifolds without adapter fittings, reducing installation labor and leak risk.
