Dwyer Instruments V6EPB-B-D-5-B | Mini-size flow switch | Brass upper and lower body | 1-1/2" NPT | Brass tee
Surprisingly small in size, the Model V6EPB-B-D-5-B Flotect® Flow Switch is designed exclusively to monitor flows of liquid, gas, or air. This Series has been extensively tested in thousands of pipeline installations and processing plants worldwide. It is weatherproof, compliant with NEMA 4, and explosion-proof (specifications include a listing). Tees range in diameter from 1/2" to 2" (12.70 to 50.80 mm) and can be installed in pipelines. The unit may be readily adjusted to fit 1/4" and 3/8" (6.35 and 9.53 mm) pipework by simply adding bushings.

Maximum operating temperature | -4 to 220°F (-20 to 105°C) Standard, MT high temperature option 400°F (205°C) (MT not UL, CSA, ATEX, IECEx or KC) ATEX Compliant AT, IECEx IEC Option and KC (KC Option), Ambient Temperature -4 to 167°F (-20 to 75°C) Process Temperature: -4 to 220°F (-20 to 105°C) |
Mounting | Switch can be installed in any position but the actuation/deactuation flow rates in the charts are based on horizontal pipe runs and are nominal values |
Rating | Electrical: UL models: 5 A @125/250 VAC. CSA, ATEX and IECEx models: 5 A @ 125/250 VAC (V~) 5A res., 3 A ind. @ 30 VDC (V ). MV option: .1 A @ 125 VAC (V~). MT option: 5 A @125/250 VAC (V~). [MT option not UL, CSA, ATEX or IECEx] |
Set Point | Adjustment: Standard V6 models none. Without tee models vane is trimmable. Low flow models are field adjustable in the range shown. See set point charts on Catalog page |
Switch Type | SPDT snap switch standard, DPDT snap switch optional |
Type | Mini-size flow switch |
Upper Body | Brass or 303 stainless steel |
Weight | 2 to 6 lb (.9 to 2.7 kg) depending on construction |
- Outstanding functionality with a special magnetically operated switch.
- Longer product life because to the free-swinging vane, which uses a straightforward lever arm instead of bellows, springs, or seals to activate a snap switch by drawing a magnet within the solid metal switch body.
- Long-lasting, leak-proof body made from bar stock satisfies application requirements.
- When it comes to maintenance, electrical assemblies that are easily replaceable without removing the item from installation can save time and money by avoiding the need to stop operations.
- Select from models featuring a field-adjustable trimmable vane or a calibrated vane in a tee.
- Fast installation using a fitting that fits into a pipeline with ease and immediately using a flange, tee, or threadolet (see to the application drawings).
- Possesses a high pressure rating of 2000 psig (138 bar) for the SS body and 1000 psig (69 bar) for the brass body, meeting even the most demanding applications.
- Meets the needs of customer-level applications with a low flow variant that has a field-adjustable set point.
