Operating limit (maximum pressure) Pressure above 300% nominal range (over-range) will result in
damage to the transmitter (200% may cause a shift in calibration).
Accuracy Less than ± 0.20% full scale (Includes linearity, hysteresis,
non-repeatability errors)
Pressure media Gas or liquids compatible with 316 Stainless Steel (diaphragm);
Silicone rubber (o-ring). All other wetted parts 316L.
Electrical Input (excitation): 14 Vdc to 40 Vdc
Output (mAdc): 4 mA to 20 mA
Linearity (worst case) Less than ± 0.13% full scale
Hysteresis (worst case)
Less than 0.05% full scale
Non-repeatability (worst case) Less than 0.02% full scale
Operating temperature range 0 °F to 175 °F / -17 °C to 79 °C

*  Transmitter turndown ratio is 3:1 for the 0–15 psig, 0–30 psig and 0–50 psig nominal ranges. 
IMPORTANT! Accuracy, linearity, and non-repeatability values are based on nominal range.

Downpipe Check ValveDownpipe Check Valve

6363 Downpipe float check valve, 3/4” NPT connections
6563-10 Downpipe float check valve, 3/4” NPT outlet, 3/8” tube inlet

   

  • Prevents siphoning or backflow of liquid through a downpipe installed in tank level gauging applications
  • Utilizes a specially designed float pin that rises up to seal the valve shut when liquid enters from the downpipe through the bottom of the unit
  • The advantage of a float check is that it doesn’t create a pressure drop that would affect the level gauge reading (Spring-loaded check valves can impact the accuracy of a downpipe or bubbler system if installed at the tank entry point)

NOTE: Not recommended for use with heavy diesel fuel oil or other high viscosity liquids. Installation in conjunction with a gate valve will permit removal of check valve for inspection and cleaning. (We recommend cleaning the check valve once per year to ensure reliability.)

Material: 304 Stainless Steel, Nylon (float), FKM (seals)
Max. Pressure: 150 psig
Inlet/Outlet: 3/4" NPT-female
Weight: 1.2 lb (0.5 kg)
