LHS Helix Flow Meter (hereinafter referred to as Flow Meter) is mainly used in flow measuring for crude oil with high sand or water content, waste water with oil, Diesel, gasoline, light oil and other chemical materials; its components are made of stainless steel, axis and bearings are made of friction-endurable materials with high anti-corrosion and friction-endurable performance.  Features: 1. Helical Rotor: it allows accurate measuring of fluids with wide range of viscosity while minimizing the affection of wax or other viscose substances. 2. Stainless Steel Measuring Components: made of stainless steel to avoid the severe corrosion to the Meter caused by high water or other corrosive contents. 3. Robust Bearing System with friction-endurable materials: this design ensures the prevention of the bearing damage from sand or stone. 4. In case of its rotating parts stall, fluid will still pass through the Flow Meter without causing any sudden pipe pressure increasing due to blockage. 5.To meet the user’s requirements the Flow Meter can be equipped with different flow convertor that provides with optional Reading modes so as to comfort the user, meanwhile it also delivers pulses or standard electrical current signals (with extra options) that might be sent to the remote display instruments or computers for data processing. 6. exquisite structure, easy installation LHS Flow Meter normally goes with different flow convertors as per user’s needs for the assigned purpose : TBS Flow Convertor: on-site instant flow rate LCD Display (5-digits); totalized (7-digit) TBT Flow Convertor: on-site totalized flow LCD Display (12-digits) TBL Flow Convertor: on-site instant flow rate LCD Display (5-digits); flow in percentage (4-digits-LCD display) All above can be equipped with optional standard DC electrical current signal output (FI Flow Convertor) TBS-G Flow Convertor: with self-power-supplier, on-site instant flow rate LCD Display (4-digits) and totalized (8-digits) The Flow Convertor is of power failure data protection, stable, reliable accurate, less power consumption performance, and it is also easy to maintain, use and operate without tight restrictions to its up/down -stream straight pipe line conditions Product Standard : Q/TDSM 12-2014 Verification Regulation : JJG 1037-2008 Verification Regulation of Turbine Flowmeter

Working Principle & Structure

While fluid forces the helical rotor attached on the glossy axis rotating, the vane of the rotor swipes the detector, which in turn, generates electrical pulse signal. Within certain flow range, the number of pulse is proportional to the flow.The flow convertor processes andcalculates the electrical pulse signal,displaying the flow of fluid through the pipeline. The structural scheme is shown on the right

Settings on the Flow Converter:

1) Operational Interface: Display meaning: 3 keys on the Converter panel, they are SET SHIFT and INC respectively a) Setting key SET: switch working, flow totalized setting and Flow coefficient setting b) Shifting key SHIFT: adjusting Total Flow Resolution in the total mode; shift the cursor 1- digit to the right in Flow Coefficient mode. c) Increasing 1 unit key INC: clean the total Flow Display in total mode; in Coefficient mode increasing 1 unit at the cursor position

Display shows 14 characters in total: FG1 and FG2 are prompt characters: FG1 shows either M or L (M=Cubic Meter L=Liter) FG2 shows P D1-D5: up-row figure; D6-D12 down-row figure

2) Setting:

(1)Operational Interface: Varying by Type, Flow Converter operational interface can display as follows: a) Instant and Total Flow at the same time b) Instant and Percentage Flow c) Total Flow Please refer to chapter 8 Converter Display Mode and examples

(2)Settings: Please read instructions below carefully before setting: a)The average meter coefficient is shown on the Quality Certificate attached to the Meter ; the Certificate should be well kept for reference; each time, after inspection or calibration, if the coefficient changes, the meter coefficient for the converter should be re-adjusted promptly. b) The biggest decimal point position for the total flow depends on the meter coefficient, in that case, the user can only move the decimal point to the backward position. During instant flow display, the scanning interval to the instant flow is 1 second , so reading is updated each second . Its decimal point position is locating automatically with full scale readings.

Meter coefficient range The biggest decimal point position & Unit   Full Scale Readings Instant Flow decimal point 0.10000～0.99999 XXXXX．XX     m3 ＜8 X．XXXX 1.0000～9.9999 XXXX．XXX     m3 8～80 XX．XXX 10.000～99.999 XXX．XXXX     m3 80～800 XXX．XX 100～999.99 XXXXX．XX     L 800～8000 XXXX．X 1000～9999.9 XXXX．XXX    L ＞8000 XXXXX 10000～99999 XXX．XXXX     L

General instructions: Following parameters can be set for Type FI/TBS/TBL/TBT, varying from Type: a) Clearing Total Flow (for TBL, void for FI-TBL) b) Total Flow Resolution adjusting (for TBL; void for FI-TBL) c) Flow coefficient (applicable to all types)

Total Flow Display clearing operation: In working mode, push SET key to enter Total Flow mode, its operational interface like:

Under Total Flow setting mode, push INC key (increasing 1 key), Total Flow shows all zero, if push SET key, Clearing is completed ; if Clearing is not required, push INC again, the total flow display resumes, then, push SET key to return to the operational interface without clearing

Total Flow Resolution adjustment (actually shows Decimal Point position adjustment) In working mode, push SET key to enter Total Flow mode, its operational interface like Clearing. The display accuracy of total flow is regarded as the digits kept after the decimal point of total flow displayed. Higher display accuracy exhibits more precisely the Total Flow, but readings’ overflow happens more often in that case, and the reverse is also true. In Total Flow setting mode, push SHIFT key (Decimal Point Position Change Key), the Decimal Point Position of the Total Flow displayed will change accordingly. Beings Satisfied with the adjusting, then push SET key for operational interface return.

Flow Coefficient Setting: In operational mode, consecutively push SET key twice (for TBS; TBT, FI-TBS, FI-TBT); push SET key one time (for TBL, FI-TBL) to enter Flow coefficient, here shows the Operational Interface

Decimal Point display is flashing at the time: push INC (increasing 1 key) to move the Decimal Point to the appropriate digit, push SHIFT key to enter the highest digit setting The highest digit flashes this time: push INC key to enter the highest effective digit of the Flow Coefficient, push SHIFT for moving to 2nd digit. Then the 2nd digit flashing, push INC key to enter 2nd digit of the Flow coefficient, push SHIFT for moving to the 3rd Then the 3rd digit flashing, push INC key to enter 3rd digit of the Flow coefficient, push SHIFT for moving to the 4th Then the 4th digit flashing, push INC key to enter 4th digit of the Flow coefficient, push SHIFT for moving to the lowest digit Then the lowest digit flashing, push INC to enter the lowest effective digit of the Flow coefficient, push SET key to save the settings, meanwhile return to operational mode, Or push SHIFT key to enter Decimal Point position setting (initial Decimal Points is flashing) and re-enter modification

3、Application Example: A Flow Meter with Meter Coefficient K=36.3065(P/L); full- scale- flow Q=40(m3/h) (already being set at ex-works as per Order); display unit: Instant Flow XX.XXX (m3/h), Total Flow XXXXX.XX (m3) Setting as follows: (1) When power is on, the meter opening picture appears, then it enters into the Operational Mode in about 3 seconds. If it is TBS, the display mode shall be “up-row for Instant Flow, down-row for Total Flow” (2)In Operational Mode, consecutively to push SET key twice to enter Flow Coefficient Setting, the interface is as shown:

(3)Enter Flow Coefficient, K=36.3065, its 5-digit effective figure=36.307 after round, Push INC once, to set the Decimal Point like XX.XXX, the Meter shows as 36.000, push SHIFT for the highest digit; no change is needed at this digit, push SHIFT key directly for the 2nd digit, no change is needed for the 2nd; Push SHIFT for 3rd digit: push INC key 3 times, the 3rd digit shows 3; push SHIFT key for 4th digit ; no change is needed for 4th; push SHIFT for the 5th digit, push INC for 7 times, the 5th digit is set as 7, the interface appears at the time is shown like this:

(4) Push SET key, to confirm the Meter returns to Operational interface.

Use & Cares
