Set-Point Flowswitches come in adjustable and fixed models.

Press Release Summary:

Adjustable flowswitches come in fixed-orifice models for 0-2 to 0-40 gph (liquid)/1.5-5 scmf (gas) and variable-orifice models for 0-1 to 0-30 gpm/1.5-10 to 1-100 scfm. They incorporate adjustable, hermetically sealed reed switches and suit line pressures to 5,000 psig. Fixed set-point flowswitches, available with liquid flow settings in 6 steps from 0.1-1.5 gpm, have solid brass or stainless steel pistons and pressure bodies and stainless steel springs, enabling use up to 1,000 psig.

Original Press Release:

New Adjustable and Fixed Set-Point Flowswitches are Rated for 1,000-5,000 PSIG Line Pressures

MILFORD, Conn. - New adjustable and fixed set-point flowswitches from Orange Research are designed for applications involving high line pressures ranging from 1,000 to 5,000 psig. The adjustable liquid and air/gas flowswitches are available with optional dials and can be installed vertically or horizontally. The fixed set-point liquid flow switches are small in size so they can be mounted in-line where space is limited.

Adjustable flowswitches are available in fixed-orifice models for low-flow applications from 0-2 to 0-40 GPH (liquid)/1.5-5 SCMF (gas) and variable-orifice models for higher-flow applications from 0-1 to 0-30 GPM/1.5-10 to 1-100 SCFM. Both model families incorporate adjustable, hermetically sealed, reed switches to control processes or initiate high/low alarms or indicators and are supplied with or without enclosures, depending on the model. They are designed for line pressures to 5,000 psig. These flowswitches are also available with optional, large, easy-to-read dials for local readout. Options include liquid-filled dials, reverse flow, red or multicolor arcs and other choices to meet specific requirements.

Fixed set-point flowswitches are available with factory-preset liquid flow settings in six convenient steps from 0.1 to 1.5 GPM. Because of their affordability and small size, they are attractive for OEM applications where simple flowswitch actuation is required. The 30000 Series switches use rugged materials, including solid brass or stainless steel pistons and pressure bodies and stainless steel springs to assure reliable, long-term, high-pressure use up to 1,000 psig, where shock and vibration are common.

Orange Research offers a large selection of affordable, rugged and reliable flowmeter, switch and transmitter designs with pressure bodies machined from solid blocks of aluminum, stainless steel or brass. Built to last, these products are known for long life and reliable service under the harshest conditions.
