Siemens SITRANS FUS1010 NEMA-4X/ IP 65 manual Flow Data Menu Items, Vs m/s

Section 2		1010NFM-3J
	FLOW DATA MENU ITEMS
	Flow	This is a real-time (updated) flow rate display in current rate units
		(e.g., GAL/MIN).
	Flow Vel F/S	Linear fluid flow velocity in f/s or m/s depending on preferred units.
	Total	This is a real-time (updated) flow total display in current total units
		(e.g., KGAL).
	Vs m/s	Current liquid sonic velocity (Vs) in m/s. The Vs value depends on the liquid
		and its temperature. This menu cell allows “fine-tuning” when highlighted.
		Press the [+] key (coarse adjustment) or the [1] key (fine adjustment) to
		increase the reading, or the [-] key (coarse adjustment) or the [2] key (fine
		adjustment) to decrease the reading.
		CAUTION: Incorrect usage will result in reduced accuracy.
	Signal (mV)	Xdcr signal strength (in mV). This is the amplitude of the transittime receive
		signals. Improper coupling, attenuative liquid or pipe could cause a low value.
	Valc %	Input Amplifier gain indication. Larger % indicates a stronger liquid signal.
	Vaer %	This shows the current percent of aeration detected by the meter.
	Alarm Status	This letter code field shows the status of the meter’s built-in alarms.
		A dash indicates an inactive alarm. Letter codes reflect the following
		alarm conditions:
		S = Transducer Spacing Warning
		E = Empty Alarm
		R = Flow Rate Alarm (High or Low rate threshold exceeded)
		F = Fault Alarm
		A = Aeration Alarm
		M = Memory Activated (Fault Suppressed)
		K = Makeup Flag (May be Latched)
		I = Interface Alarm
		P = Pig Alarm (option)
		Z = ZeroMatic alarm
	AnCal	Flow Rate Simulator for calibrating external devices, etc. Highlight this item
		then press the Right Arrow to enable numeric entry. Type desired simulated
		flow rate. Be aware of the units prefix (K, M, etc.).
		NOTE: AnCal remains active only while you remain in this menu cell.
	HiFlow	Most positive expected flow rate for application (adjustable).
	GAL/MIN
	LoFlow	Most negative expected flow rate for application (adjustable).
	GAL/MIN

Vs m/s

This menu cell shows the current sonic velocity in m/s. If you move the cursor to this menu cell you will note that it switches from the usual arrow ( ) to a question mark (?). This indicates that you can increase the reading by pressing the [+] key for coarse adjustment or the [1] key for fine adjustment; or reduce the reading by pressing the [-] key for coarse adjustment or the [2] key for fine adjustment. Sonic velocity (Vs) adjustment is a diagnostic tool intended for our technicians or experienced users only. Improper use will affect the meter accuracy.
