2. The MiniWave emits an ultrasonic pulse which is reflected from the surface of the liquid being measured The reflected signal is processed using specially developed software to enhance the correct signal and reject false echoes Automatic sensitivity control allows the unit to dynamically adjust and improve the received echoes for the best possible measurement outcome Model Type MWN1A MiniWave with 2 NPT thread MWB1A MiniWave with 2 BSP thread E A Removable lid with viewing window B Electronics housing C M20 cable gland D NPT or BSP thread E Transducer face Sor a e HAWK Dimensions amp Wiring MiniWave User Manual Dimensions Wiring 85mm 3 4 Flip Lid to access terminals 185 mm 7 3 2 BSP or NPT THD M20 Blank Plug Flange FA2NB 4 2 ANSI Polypropylene Flange for NPT threaded units FA2BB 4 2 ANSI Polypropylene Flange for BSP threaded units 4 x 19mm 0 75 HOLES THROUGH 120mm 4 7 P C D ae 2 NPT or BSP INTERNAL THREAD 152mm 6 0 15mm 0 60 Installation MiniWave User Manual Mounting e Sensor should be mounted 1 3 the diameter of the 2 NPT MWN1A vessel from the vessel wall or 2 BSP MWB1A e Unit should never be closer than 250mm 10 to the liquid surface e Do not mount over or near objects which can interfere min 250mm 10 with the unit measu
