S-111, S-112, & S-114 Flo-Meters

For liquid flow metering with integrated rate display, the S-Series Flo-Meters have been setting the pace.  Their advanced Pelton-turbine design provides large turn-down ratios, fast response, and repeatable accuracy.  Combined with an affordable price, you cannot beat their value.  A 0-5VDC analog output is standard.

If you require an inexpensive plastic flow meter to measure flow rates, the S-111 Flo-Meter is the answer. Including an analog 0-5VDC output and a 3 1/2 digit display of flow rate in engineering units, these flow meters are perfect for any laboratory or test facility.

For higher pressure applications or where metal may be required, the Model S-112 & S-114 may be the solution. Both are rated to 500 psig. The S-112 is made from brass, whereas the S-114 features a stainless steel flow body. The S-114 also features enhanced 1% accuracy for critical applications, and comes standard with an NIST certificate.

Wetted Parts

Either a cable assembly or power adapter is required for operation (see below).

S-111: Ryton, acetal, sapphire, glass, epoxy, Viton O-rings and acetal fittings standard. 
S-112: Brass, Ryton, acetal, sapphire, glass, epoxy, Viton O-rings and brass fittings standard. 
S-114: 316L stainless steel, Ryton, acetal, sapphire, glass, epoxy, Viton O-rings and SS fittings standard. 
EPDM O-rings are available instead of Viton on any unit at an added cost - use suffix "Q".
