3 IP2046/IM Nov 2006 1.0 Introduction The MSP400 ultrasonic level transmitter is designed to be mounted above a liquid and will measure the distance to the liquid surface. When programmed with details of the vessel, sump or open channel, the MSP400 will compute level, contents or flow and give a 4-20mA signal proportional to the chosen variable. 2 [...]

4 IP2046/IM Nov 2006 2.2 Pressure Equipment Directive The MSP400RH transmitter does not fall within the PED definition as enclosing a pressurised fluid, so is therefore outside the scope of the Directive. Accordingly , the Declaration of Conformity does not list the Pressure Equipment Directive. 2.3 Specifications Materials of construction: T ransd[...]

6 IP2046/IM Nov 2006 3.0 Installation Important safety notice : The MSP400 is designed for safe area use only , and must not be installed in a hazardous area, even if the power is supplied through a barrier device. General a. Installation must be carried out by suitably trained personnel in accordance with the applicable code of practice. b. If the[...]

7 IP2046/IM Nov 2006 • If the transmitter is mounted in an enclosed tank, avoid mounting the transmitter in the centre of the tank roof as this could act as a parabolic reflector and create unwanted echoes. Avoid applications where heavy condensation could form on the transducer face. • If the transmitter is mounted in a stand-off or nozzle, it[...]

8 IP2046/IM Nov 2006 It is important to note that the bottom reference of the transmitter should be related to the centre of the invert of the primary device, NOT the distance to the channel bottom directly below the transmitter . 3.1.3 In-tank effects • Stirrers or agitators can cause a vortex. Always try to mount the transmitter off-centre of a[...]

9 IP2046/IM Nov 2006 • The liquid surface at the point of measurement must have a stable, smooth surface and uniform approach velocity . It must not be affected by baffles, foam, hydraulic jumps or any other object likely to cause flow disruption. • The primary element should be free from any situation where it is likely to ‘drown’ (refer t[...]

10 IP2046/IM Nov 2006 3.2 Mounting the transmitter above the liquid surface. A 2” thread is provided to mount the transmitter . The user should check the thread form, which will be either 2” BSPT (MSP400RH-B28) or 2” NPT (MSP400RH-N28). The thread form is clearly marked on the hexagon of the transducer body . Note : The MSP400 is designed to [...]
