Supported Applications
The Omega FTB-800 Series consists of liquid turbine flow meters designed to measure fluid flow. The device operates by using a turbine rotor whose rotation speed is proportional to flow velocity; the rotating blade cuts magnetic field lines, inducing electrical impulses that are amplified and transmitted as a 4 to 20mA signal.
Operating Conditions & Performance
The series supports process temperatures from -20°C to +120°C. Accuracy is specified at ± 0.5% of reading with repeatability of ± 0.1%. The meters feature a hard alloy bearing thrust type sensor for precision and wear resistance, offering minimal pressure loss and high repeatability.
Pressure ratings vary by connection size:
- 913.5 psi — all NPT meters up to 1"
- 362.5 psi — 1-1/4", 1-1/2", 2" male NPT
- 232 psi — 2-1/2", 3", 4" male NPT
A warning states that pressure in excess of allowable rating may cause the housing to burst. Severe pulsation and mechanical vibration will affect accuracy and shorten meter life.
Configuration Options
The FTB-800 Series is available with multiple male NPT process connections, including 1/2", 1", 1-1/2", 2", 3", 3-1/2", and 4-1/2". The output signal is a standard 4 to 20mA current loop.
Electrical connection requires two wires from the flow sensor (24V+ and 24V-) connecting to an external instrument that supplies 24VDC power.
Wetted Materials
- Body: 304 OR 316 Stainless Steel
- Rotor: CD4MCU Stainless Steel
- Rotor Support and Bearing: 316 Stainless Steel
- Rotor Shaft: Tungsten Carbide
The operator must ensure that the operating fluid is compatible with these materials, as incompatible fluids can cause deterioration of internal components.
Key Product Differences
Variants within the series are distinguished by model number and physical dimensions corresponding to their NPT connection size. Model numbers follow the pattern FTB-800 - <Model Number> - <Size/Type>, such as FTB-804-I, FTB-815-I, and FTB-830-I.
Overall dimensions vary by model. For example:
- FTD-804-I and FTB-806-I (NPT 1/2"): L = 225 mm, H = 141 mm
- FTD-810-I (NPT 1/2"): L = 345 mm, H = 141 mm
- FTB-815-I (NPT 1"): L = 75 mm, d = 15 mm
- FTB-830-I (NPT 1-1/2"): L = 120 mm, d = 32 mm
- FTB-840-I (NPT 2"): L = 140 mm, d = 40 mm
- FTB-860-I (NPT 3"): L = 175 mm, d = 65 mm
- FTB-870-I (NPT 3-1/2"): L = 200 mm, d = 80 mm
- FTB-880-I (NPT 4-1/2"): L = 220 mm, d = 100 mm
